I think I actually started this a year ago.I bought a 5.3 out of a wrecked Silverado with almost no k's.(11,000 IIRC)I went back and forth,should I,shouldnt I...I actually called the fella who was going to build it for me and asked him to sell it for me.
Then,as luck would have it,my car was giving me grief early this summer.D-jet hassles,etc.No surprise,I dropped a valve seat.At this point I was pretty sick of DJet(had some sweet Italian Webers in the wings lol),and really wasnt feeling the big 4 idea,though I had collected parts already.I just wanted to drive my car. I wanted to be able to turn the key,and get instant fun and reliability(motor wise),and yeah wayyyy more power than the 2.0 was giving me.Needless to say,the dropped seat made me make up my mind much quicker which direction I was going to go.After reading a bunch of V8 threads,and some you tube stuff(Especially Byndbads vids and car,that thing just kills)I put the wheels in motion.
The motor I bought is an LS Iron blocked engine,and came with FI.But Truck FI.(quite tall)My buddy Murray at Real Horsepower had been doing carb'd LS's for a while,I like carbs,so we converted it to a carb'd motor.We used the MSD programming module to run the coil packs,bolted up a LS carb manifold(Edelbrock) and put on a Holley 670cfm Street Avenger.The other thing about the 5.3 Truck motors are the pan.Quite deep.Too deep!No sweat,Murray had a brand new takeoff from a 2010 Vette he did in 2010. Its nice and shallow,lotsa clearance.
Week 1-12
I phoned Renegade,ordered the loot and waited.In the meanwhile I mounted the fuel pump and filter(Did Sir Andy's cool fuel pump trick) and started to cut up the front of my car a bit. (The guy in the car is my buddy Andrew.I owe him big for all his help!)I tig'd in woven SS mesh to keep birds and 2x4's out.The rear firewall had lots of shitty old brown glue on it,and the battery tray sucked too.I welded in a new tray and got my body guy to respray the firewall as well as the mesh.(After lizard skinning it)
I ripped out all the carpets,fixed an ugly spot under the drivers side seat and welded the Engman kit in.My body guy sprayed lizard skin over the entire floor/inner firewall.
I also repalced the throttle,and clutch cables as well as ran a new 3/8" SS fuel line through the tunnel.Installed Racer Chris's Sway Bar.
I had a nice uncracked dash top saved for this,so it went in too.I also installed a new black carpet kit for good measure.
Bought a high torque starter.Put in all new brake hoses and 320 calipers in the front.Installed the tee.
Whew!
Week 9
Cooling system from RH came! Installed it and ran some wiring for it too.
Week 12
The rest of the RH stuff came!(In the most destroyed boxes I have ever seen,but thats another story lol)
I dumped it all off at Real Horsepower.Murray went on vacation for 2 weeks!!AARRGGGGG!! Im still learning how to be patient!lol
Anways,Murray came back and he bolted the whole works together.The one thing RH doesnt make a provision for is the Iron block LS's are missing a tapped hole for their alternator mount.(We used a single wire 120 amp alt BTW)Murray and I made a slick mount that you can see in the pics.
I called Murray and said"Hey,give me a shout before you bolt that thing in the car,I want a couple of pics!"He told me i'd better get my ass over there now,cause it was in progress!
Murray's a cool guy.Hes not a Porsche guy tho.He has his shop full of beautiful(customers,and his own) hotrods.When I told him what we were up to,(the conversion I mean) He didnt even bat an eye.He was in.I told him I wanted to do as much of it as I had time for,and that I had to do the exhaust.I told him I would take the car elsewhere to work on the stuff I wanted to do myself,and he refused.Murray is a cool guy.
The other cool thing about this whole thing was the reaction from the regulars,and his new customers too."That is going in there?? That is super cool!!"My little car was on the lift,surrounded by $100k Hotrods,and it was the Belle of the ball.
While I was there,there were at least 4-5 phone calls to Murray from his cronies."It it running yet?Have you driven it yet?"
Anyway,Murray and I probably did the whole install of the motor/transaxle in about 4.5 days,including Andrew and I doing the exhaust.Murray held up the old wiring harness and said"Tom this thing is kinda scary!Im not using it!" So,all the wiring got a nice upgrade in the bay.I used the Parkerflex coolant hose,expensive,but very tough and can bend into a tight,tight radius with zero collapse.Yes I ran hose under the car.It bugs me.(I wish I was more patient and ran SS like I will do for next season,but I simply did not have time.The sun is running away!)
The goodies from Renegade all worked as they should.Thier instructions are No,really they need an update and I told them so!Hi Scott,Steve, Ian! Despite the "Instructions" The parts,and the guys at RH are top shelf.I called,I got answers.Really good guys.
Murray and I started the car.It was almost alien!Ive started the car many times,but this time it lit up in 1/2 a revolution,and sounded crazy!It was odd at first,my little green car sounding that way,but not in a bad way.More like a "Oh thats much better"kinda way!We filled it with water(Also weird as hell)and follwed the burping procedure. That was last night.This morning I got to drive my car!
Its crazy.The car feels the same,but just wayyy more assertive.Im taking it easy,because of clutch break in,but wow.Its so much more fun you couldnt beat the smile off my face with a baseball bat.My car is "fixed" The cooling system works flawlessly,it sounds tough,and is scary fast.I loved my car when it was stock.It still feels that way,just more.
I had two guys tailgaiting the hell out of me on the way home(My maiden voyage of considerable distance,45 min)to the point that I pulled over.They also pulled over,and I immediately thought"Shit!somethings on fire!" Nah.They wanted to know what was in the car! Jeesh!
Anyhoo,here is some pics of the process.It was fun as hell.(though,it would have been cooler if it was done 9 weeks ago lol)
Thanks to

Heads up!This is the bracket you need to fab for the LS IB to make RH's Alt bracket fly.Heads up!This is also a terrible photo!Ill dig for a better one.
Attached thumbnail(s)
WOW that is one clean install!
Congrats! You should be proud! (Tig'ed SS exhaust is a very nice touch)

Cool bonus for me.The Tuner guy shows up.Hes a highschool pal of mine ive not seen in 19 yrs!The very first drive I took in the car,Brian(The tuner/Buddy of mine from GR 12)was sitting in the passenger seat with a cable flapping away over the targa bar programming away while we bullshitted about the good ol days!
Cheers!

Very sweet.
Very clean! Like everything about the car....but a carburetor??!!
It's like getting to the Olympics, and then sleeping in past the alarm.
...Very sanitary man!(monster power plant)
Very Nice! Couple of questions.
Why the carb on backwards? Easier to install the throttle linkage?
Stock linkage?
Did the Avenger need alot of adjusting?
Where did you get the metal mesh?
Awesome install. You do really great work. Though, all I thought of when I read the title was:
Looks great. Bet it drives great as well. Hopefully that awesome exhaust doesn't melt any wires near by. But I suspect as clean as this install is, that has been addresses and any melting danger is just the perspective of the photo and not a real problem. Does that beast run an air cleaner, and how does it fit under the engine lid?
Nice, nice, nice.
Wow!
Nicely done.
Hope to get a chance to see/hear it sometime!
That pretty well ups the ante around here...!
Can we see the front bumper? Curious on how it looks. The rest of it looks amazing!
Congrats! Your exhaust looks super clean (and the entire install). It's kinda magical the way it gets up to speed so quickly, with so little effort. I've driven a lot of powerful cars, but the way the front end gets light under acceleration (in 3rd or 4th!) is really a rush.
OK, you all should know that this conversion was done in secret and that no animals where used for testing during process. Oh ya, and I knew all about it the whole time!
That is one insane transplant SPEED!
Now Just DRIVE!......and get a real camera
Cool build.
Here is the front end,and a couple of shots from a distance.What conversion?
Temps stay steady at 190-205.
i have a 5.3 in my jeep it runs 193 at slow speeds when the fan is on 197 at highway speeds and 205-210 when im beating on it. looks like your cooling system is working perfect
Nice build. Very clean.
I always thought that the all aluminum LS motors run hotter than SBC. That is why they are a good fit for the 914 conversions.
EDIT: Yours is the cast bottom end...nevermind.
It also helps that you're in Vancouver. I've sized my cutouts for stop-and-go traffic and 100-degree ambient temps here in the Pacific Southwest.
Can you give some info on your sway bar set up? I have a similar bar, but I am having trouble with finding the arms and links...
Thanks!
Nicely done!
Nice exhaust!
Why carb, and why not keep the EFI?
Seen this car Sunday while up in Canada for races at Mission.
It is a very nice car and has a nice exhaust tone. Really is a nice car
Speed metal army can now come down and play with us PNW people.
Hey!
I haven't updated this for ages, but I thought I would for the sake of having all my build documented for myself through changes/upgrades etc. I am planning further mods so I should do this before I get ahead of myself and forget things.
Its also a chance for some gratuitious photos of my car.
So, update on the swap after a year:
We have had the best summer in years and I drove the heck out of my car. No issues!
(Oh wait, late last summer I roasted a CV, and went with Renegades cv/shaft setup, no issues since )
I dig the power. The 5.3 accelerates fast enough to scare the crap out of me, yet produce a huge grin at the same time. Light switch oversteer for fun in the form of black marks/smoke, also fun as hell. Especially in a 914 !
Since I updated this I have:
-Installed a new Hella H4 kit. Now I have 2 lights that are the same! Yay! Plus they work nice. Much better than OG
-Had an odd electrical gremlin fixed that was worth every cent. Car would blow a fuse when I signaled left 20% of the time.. Turned out to be a short behind the guage cluster. Yeah. I never would have found that.
-Found a super low profile air cleaner that fits underneath my stock lid. It doesn't seem like much,but the LS style stuff is a shade taller than the SBC.
-I rebuilt my shift linkage, nothing fancy or picture worthy, but it works sooo much better than the crappy rushed version I slapped together when I was finishing my car. What?I was stoked to drive at the time. The new linkage uses stock parts,and is just a slightly longer creatively cut and mitred version of a stock linkage.If anyone has grief with the LS motor(corvette pan) linkage,LMK. Shifts nice now.
How about stuff I have pics of?
Quickfuel Q series annular 750 mech secondary! Good stuff! Annular boosters are FI like! Weighs a 1/4 what my holley weighs too. Plus it looks cool.
I also put a real regulator in there.
I also built a GT lid from Shea's tutorial. It looks cool, but I just dig the stocker.
Photos in next post..
The GT lid is cool! I built it using Erics tutorial, and it came out pretty nice, but I built it for looks, not cooling, and my green lid wins.
What say you??
I have never had any cooling issues, so fashion outweighs function this time.
My old fuel setup needed a revamp! I installed a new filter,some SS valves and a Holley Billet gerotor pump. I had to fab up a new mount , as the new pump was bigger than the Holley "red" it replaced. The "red" was so loud it was crazy! The new pump is the ticket so far. Quiet, and consistent.
There has been other stuff, but I cant think of it at the moment... Here are some pics of the car in its current state. I am currently torn about flaring this car. I don't know exactly why. I like the sleeper aspect, but cant leave well enough alone. Big bumpers and flares?!?!! That's crazy talk..
Waiting for the next sunny day...
Very nice and clean build. I love it. Heavy in the mouth though. (being brutally honest)
If you want a $.02 from nobody, the BUBS have to go first. They make me barf a little in my mouth.
Before going full flare (which is the ultimate end where we all eventually end up......) That weasel on my other shoulder says, stretch those a little and fill them out like pumped biceps in a too-tight t-shirt.
Point being, work up. Fill your sleeves before you buy bigger clothes.
Absolutely beautiful!
Jealous...in a good way....need to see it in person!
Paul
BTW
Stock lid looks best, if no cooling issues. I think the GT lids really only suit the GT type cars...the stock lid helps the lines flow better.
Awesome to hear that you are still digging it a year later!
It's beautiful. Bumpers and all. You don't need to worry about what is in Rand's mouth, he'll put anything in there.
Can you give us an idea on average MPG with your carb setup?
Thanks!
Beautiful car!!! I love that it is such a sleeper. I would not change a thing.
Looks awesome as is...but I wouldn't yell at you if you backdated... chrome bumpers would SET THAT PAINT OFF and work really well with your wheels... It looks so nice as a narrow bodied car. Avoid the flares unless you have to have wider wheels for traction.
I've got a nice IMSA front bumper. Great for a car with a radiator. Was going to use it on my LS1 conversion. Plans have changed & while I do like it. I would do it over the BUBS bumper for sure. I hate those dang things. I've always kinda liked the IMSA. So if you decide to change out the bumpers
Even though I'm not a fan of the BUBS your car does look great as it sits
Car went under the knife today. Steel flares, new fuchs, bumper backdate (bumpers painted black) and new paint on the way. Progress pics to follow.
I pulled the late bumpers myself. Holy crap, I lost a TON of weight! And the car is a good 24" shorter. Im stoked!
For the bumpers, think fiberglass!!! Very lite and they can look good
is the 5.3 all stock except the intake and carb?
no cam or head work?
Too bad. I like the BUBs. Other than the weight issue. They are a visible evolution of the 914.
Says the guy who back dated his '74 bumpers...
Lots of pics please.
Looking forward to the pics progress!
I've got to admit. The only time I have liked the look of the bubs was on a flared car. They really set it off nice
Nice v8 conversion !
I'm doing my first one right now, some questions:
I noticed that the drain for the radiator is up at the top, is the radiator mounted upside down?
Did you source the radiator, and fab the shrouding, or are these Renegade items?
It appears as 2 coolant fill tanks are mounted in the engine bay. Or is 1 just a fill point, and the other just the osmosis overflow tank?
Enjoy that Bowtie power
Marty
Not to hijack here, but I've got some pics of the Renegade system in my car. Pretty nice from a plug-n-play standpoint, as it comes with pre-bent shrouding, pre-wired fans and relays, thermostatic fan switch and a single fill point (driver's-side engine bay). Does take a lot of bending/finessing the aluminum, but in the end it's a pretty sanitary install.
Some crummy first photos! Progress!
Some super awesome rocker dirt. Id say a pound and a half or so. Good news is , the longs are still nice.
Rear bumper back dated! Looks odd to me.. Needs the valence. Also not used to the bumper itself. They will be painted black, all dings, holes etc eliminated of course. The bumper tops will be FG ala Mark/Mikey 914. The rubber ones aren't great on these particular bumpers.
And one more.
Top view. Fits good!
All those holes you see there? No more rear reflector for me. I liked it, but it was slightly crooked, and now is the time to say goodbye.
Yes, that's a broom handle holding up my trunk. I need to get that cool trunk shox kit from Craig. The T bars wouldn't fit with the conversion.
And of course one of my new friends in the trunk.
Wow, that looks amazing, would love to see it in person!
A V8 in a 914??
Hey Tom ...need some 16x8s
Some more pics of todays progress. Flares screwed on before slicing through and tacking/welding. Both bumpers on.My poor little 6"'s look a bit overwhelmed!
Slightly fatter butt. Its hilarious to me how after I have built this look on the 914 visualizer so many times, it looks just like the renderings.
Im currently searching for tires.. Any advice on some 15" rubber would be great!Its pretty slim pickins for fat 15" stuff that's not a 6" side wall.
Its confusing to me how you can keep straight of left and right flares..
They look normal to me.
Hey did you get a chance to do a quick lap with the new bumpers? Mine felt so much lighter and more nimble. Probably mental but it sure felt good!
I didn't mean your flares looked like they are on wrong, sorry about that! I know that there are differences with the flares from the right side and left, from looking at various pictures and it is hard for me to see the differences.
Some more progress. They are TIG all welded on and the finishing begins! I will take some decent pictures on a real camera when I get the chance. The 7" Cookies look tiny in there!
Wow, that looks great. Love the color too.
Don't let the sparks hit the glass.
Looking good I`ll have to come check out the progress when I`m done trying to get me car a rolling chassis for the big move to Maple Ridge..lol a little closer to u now!
looks like you used the dan root method to cut and weld.
Look at that nice big ass!
Bye bye 911 mirrors, bye bye rear relector!
Fat RE-11's!
The flares were from Porbmw, the wheels from the mighty pete stevers.
Somehow its way more fun to drive now.
And one more..
The ol' cell phone doesn't do it justice. Some small things to do still but that's the fun part. I made a drawing of the bumper grille to match the fog grilles as close as I could.. The bumper has a slight curve to it. I altered the dwg to fit that. It worked pretty good.
The air inlet in the bumper looks sweet !
Marty
Very nice looking car. I too like the color and happy to see the new bumpers
Good Job
Looks awesome!
Damn! That looks good!
Double damn!! I am stalled!!
Was thinking about you last weekend, was going to email you to see how you were doing, was pretty confident you'd get your sorted out before I get my diversion done.
Looks great, love that fat ass!
Am going to be away for about 3 weeks, hope you are around in August, would love to see it in person.
Was jealous before, now even more so...in a good way, of course
Hi sir, do you mind include the old picture as before and after which I believed you have on the same spot?
Very nice
How about posting a front-on shot of that bumper? I know I am going to have a front cooler in my car and am still considering front bumper modification options. Thanks and Happy Fourth.
Wow! It looked great before and it looks even better now! Somehow you kept the "theme" of it exactly the same. Those wheels are flippin' sweet. How do you like the handling with the wider track and without those heavy bumpers at the ends of the car?
Absolutely sweet man . I love green 914's
Looks fantastic! Congrats!
Your front spoiler is a favorite of mine. I have the same one on my LS1 car, but it's been repaired a time or two. Do you know if anyone makes this particular spoiler anymore?
Andys
Thanks for posting before and after picture!
Awesome car, gotta love the green too! What size wheels did you end up with?
914 day came around again with awesome weather! Oil change!
Went for a nice rip into town for a coffee, hit up the local track. The vintage racing crowd was there! Thinking about it now, this is the event that I had met NORD a couple years ago. Drove home and noticed my fans seemed to be sluggish firing up. Weird..
Scary! The hot lead that supplies the fans had rubbed through the insulation on a ground that was way to close to the rest of the relay/wiring etc. Not going to point any fingers, it did take 3 years of driving but a revision of that particular wiring setup is needed....
Fixed! And went for another drive. All better! All told I got about 4 hrs of driving on "914 day"!
Along those lines, I'm wondering if the torsion springs for the rear trunk lid, can stay or will they have to go, to accomodate room for an LS3?
