While trying to troubleshoot my ignition issues, I had a backfire and this happened.

Anyone have a distributor solution that's not a 123 you like, My Mallory seems to be my issue. Watching the ignition with a timing light it just dies off and comes back without anything being a determining factor.
I checked engine to battery ground, power to the coil with a test light while running.
Battery charge level. Plugs, cap, rotor, points are all new. Dwell is set correctly.
it just dies randomly. I cant trust the car at all.
Drove it a little today and like i said, had a back fire from the spark cutting in and out and this happened today.

So this should be a fun fix. popped a hole in my SSI.

The zmallory optical dizzy is notorious for intermittent performance when the module is weak. I went through this for a couple of months, all the time thinking the module was ok. Soon as I replaced it, problem solved… (IMG:style_emoticons/default/smile.gif)

Bought a cheap distributor to put in the car to isolate the ignition issue.
Runs fine now, curve sucks but its drivable.
Since its a points distributor I guess ill change the condenser again and see how it goes.
This motor is due to be pulled and sold any day now. I have a 2.8L twin plug to be assembled and put int.
Just need more time thats all.

Somehow managed to get about 3 weeks of time to work on the motor that I planned on putting into this car so here are some pictures.

I am building a Mag case 2.8L meaning 92 bore 70.4 stroke.
Yes I know its probably a hand grenade but it is what it is.
Mark sold me the 2.7 core motor in I want to say 2015 or somewhere around there.
And Here and there little by little I have worked on it or bought parts.
Most of what put me off was I bought a 911 in the mean time and that needed a motor.
Since the 914 ran it was less of a priority to fix than the 911 that while it did run would knock on even 100 oct fuel.

I am using CP pistons with a coating DC60 or 65 Cams. All of my machine work has been done by Competition engineering.

That is not to say that this engine build has been without its bugs.

This is what the core motor looked like when I removed the heads.
The motor refused to turn over completely when i bought it. Turned out someone slightly bent the valves and that was the cause. No matter it turned clean now. however it was far from clean.

Luckily for me I was able to have a friend who now has his own engine building shop allow me to use some of his shop space.
he and I are both people who generally prefer to work in our own way but happily we get along fantastic.
While I assembled the motor under his guidance I ate all of his famous amos cookies.
Pretty soon it was starting to look like a motor. This lead us to our first problem

Originally I sent my case up to Competition engineering paid my bill and when it was returned no machine work had happened. Errors happen and luckily Walt is great.
I returned the case had it machined and it made its way back to me.
Ultimately we did find that the main bearing clearance was a bit on the big side however I chose to run a large oil pump and considered it to be safe. It was only a few tenths of a mm out.
Crank and rods mated up perfect. The crank measured out absolutely as new. A lucky score for me. Marine crank shaft had cleaned and polished it for me as well as balanced it.

I spent a ton of time mixing and matching pistons, wrist pins, rods together in order to get all of the rotating mass within .5 of a gram. Happy with that I began assembly.

Next came laying out the case.
After I cleaned it years ago I had found a good deal on a 964 Oil pump.
This pump was never designed to go into this 2.7L case but uh, nothing a big ole grinder and some time cant fix.
We got it to clear and we were good to go.
However during this In my "replace all the wear items" phase I had bought some gears for the Intermediate shaft. Turns out they are garbage and would have grenaded the motor.
Thanks to Cornelius for this bit of info. I being the wise and annoying person that I am had kept all of the original parts so i simply swapped them back. they were not in the best of shape since someone had been in the motor before me and shimmed the cams and timing chain alignment poorly.
Once that was taken care of at a neighboring shop (They had a D type!)
we were on to lay out.
I am using the Iwiss racing chains the 964 pump and have ARP rod bolts for the rods.
That covers all the internals meaning I get to find my next set of problems.
Progress is often slow while we are doing this via its a working shop or I am plain screwing off. With that We had the case sealed up in no time. I was playing "we belong together" as we did the work. Hope that helps.

Sweet looking motor. A clean and tidy shop speaks well of the builder. Will this throw a hitch in smogging the 76? (IMG:style_emoticons/default/beerchug.gif)

And, for those who are unaware, there are no smog requirements in MN.

Looking forward to the 6 dude!

Once the case was assembled we moved onto checking the compression ratio and setting the deck height.
Attached Image

While trying to set the deck height it became apparent that the cyls would not fit into the case, however this was not the fault of the cyls.
Attached Image

Turns out via some phone calls that the machine shop I used places the case savers .25mm further out. this in fact then adds up to a small but significant .5mm.
As with any problem its never just one thing, I following the advice of Cornelius and other notable names we like my last flat 6 build chose to use 993 studs.
Only plan of action became to open up the holes on the cyl for the larger studs
not fun.



The goal here was to meet or slightly exceed 10.5:1
Unfortunately either our measuring skills were not good or something was wrong.
Attached Image


we kept coming up with somewhere around 9.5:1 not a bad number but not what I had asked for And not what the piston information card indicated.
Attached Image

Luckily for us CP Carillo is right up the road. after some back and forth on the phone about the issue and how we measured I dropped off a piston to have them confirm what the piston exactly was.
Unfortunately it turned out they were made incorrectly. The base piston was in fact a 9.5 however the modified file never made it to the CNC machine that cut these.
They agreed to build me another set of pistons however it was going to take 3-6 weeks.

I Just have received them back but it will be a bit before I can get back onto this.
Of course this means my 4 cyl motor was being fussy after being parked on a incline. Unsure if that's a artifact of 44IDF carbs. If anyone knows let me know.

And a picture of the valve spring set up on the heads.

Somehow I chopped this picture out of the last post.
This is a Semi current picture of what the car looks like as of right now.

Now hold on a minute... OT, but having just sold my E9, I have to ask about the 3.0 CS /Batmobile wing in that pic. Your car?

That is a real batmobile, not my car.
It does have a S38 3.8L on weber side drafts.

If you remember from a while ago about Adam Carolla selling one? this is that car.
I worked for the person who bought it and wound up doing a ton of work to it to get it race ready.
He also has a E9 street car with a S52 in it. its really beautiful and he uses it as his daily driver. Ive driven it a fair bit and its about the right amount of power for that car.
It was built for him by a friend (Jeff Tighe) who also built a white S54 powered car. That car was a monster.

That's a cool garage space, is that up here in MN or back in CA?

Those pistons look so nice, you have the new ones back now?

The picture of the car in the shop was back from when it was in California.
As far as the pistons go, I do have them back I just need to make time to go home and continue to put it together.
First the overcrest rally.

I'm just going to keep adding to this because why not.
After a while I made it back to California for like a month. Ultimately the motor is closed up and finished and that's what these next pictures will be detailing.
I was going to dump the motor into my 911 and see if i can break it in in that car while i do some work on my 911 motor but, things don't always go according to plan.
Oh well. ill be back at it in about a month.
Not having a job right now is both good and bad. Luckily a lot of the parts if not all of the parts have been bought for this over the years so its not costing me a ton of money. That makes all of this easier.

I found this picture I took when building my 911 motor and I found it a fun example of how different a flat 6 motor really is from the type 4.
CG-914 and his wife were in the middle of rebuilding a type 1 motor at the same time we were doing the 911 motor.
Im happy to say that motor is running pretty well and is a daily driver now.

I have new pistons staged and ready for assembly and carried on opening up the stud holes on the cyls to make everything fit.

Attached Image
Attached Image

This included having to clearance the base gaskets as well.
We re shot the deck height and checked compression.
A single 1.0MM spacer was all I needed thankfully making it easy to clearance.

Final compression ratio came out at 10.60:1 Should have a ample amount of pop in a 914.
Once all the cyls were fit into the case, about two days of work I was ready to put pistons on and carry on. that will be the next post.

Oh and as far as the E9 stuff I am more than willing to take a slight detour,

Here are some pictures of the car you can see in the backround.
It as mentioned was Adam Carollas car. He bought it and promptly never did much of anything with it.

Attached Image
Attached Image


We found several problems with it the short list being way too much fuel pressure, shit exhaust quality, fuel cell foam dying, rear diff pulling the structure apart in the car.
I did manage to find the original engine builder, its a 3.8 with about 13:1 compression and should make right around 400 hp.
The current owner also had a Street driven E9, the black one seen here with a S52 put into it. car has bluetooth, AC and all the modern stuff you would hope for without being even remotely obvious about it

The guy doing these street cars also had built one of my fave street cars ever
A CSL look alike with real CSL interior and a S54 inside. To say the car is bonkers at full throttle is pretty fitting. but the owner put a ton of hard miles on it without ever really having any problems. We did suspect that it is a bit much on the chassis however since they are not known for being stiff..
