What is the diff in weight between a type4 and V8? If the V8 has aluminum heads, what do you save...50lbs?

BH

man, a V-8 is a heavy animal..... I have no idea. The block of a V8 alone weighs more than a TIV complete longblock for sure.

V8 longblock (smallblock) 550lbs add rad, fan, hose, water, etc...
Plus the centre of gravity is higher.

T4, what around 280lbs full dressed?

I agree with Mark Henry's weight estimates.

SBC heads:

Early iron heads weigh the most - later (late '70s and newer) iron heads weigh less but can be prone to cracking.

Chevy aluminum heads weigh a lot less that aftermarket (Edelbrock, Trick Flow, etc.) because the aftermarket are much thicker.

So going from early iron to Corvette aluminum saves a lot (maybe as much as 40lbs?), but late iron to aftermarket aluminum gives very little savings (<20lbs I would guess).

My brother laughed when he heard a T4 short block can be picked up and moved. His ford 289 was a big motha'.

Yeah. I think the sixes weigh in at around 400, right?

The subaru motor is slightly heavier than a TIV, and puts out 280horse & 280ft/lbs or so. All the weight is on the bearing line.

Scorchio.

I have a spare 1.8 subaru single turbo engine that needs a rebuild if anyone is interested in doing a project. I have an early style (tailshift) motor mount bar for it. I will even help with the project. It has a distributor, so you don't have to do electronic ignition, unless you want. It puts out 150 horse in stock trim with low-ish boost and no intercooler. That can be improved with better boost control.

Here is a copy of a thread from the Pors-chev group about engine weight. I know this is a all aluminum LS1 vs a 3.0 six.

I have seen this issue pop up on this forum from time to time well,

I finally got an answer to this myth.

I took the time today to take my 1980 911 3.0 SC engine and 2000 GM LS1
Corvette engine to the scales to weigh them and this is what I found
out:

My fully dressed 1980 3.0 Porsche engine ready to install weighed 472
lbs. Factor in the weight of the oil in the 10 quart oil tank needed to
support the 3.0 engine, then your engine plus oil tank weight jumps up
to 490. 5 lbs. at the rear of thevehicle.

(One gallon of oil is 7.4 lbs. Ten quarts is 2.5 gallons, 2.5 x 7.4 =
18.5lbs.)

My fully dressed 2000 LS1 Corvette engine ready to install with the
engine computer and wire harness, complete exhaust system, engine
mounting brackets, AC compressor, alternator, custom water pump adapter,
transmission adapter plate and flywheel weighed 434 lbs. This is a rear
vehicle weight savings of 56 lbs. over the Porsche 3.0 engine.

I did not weigh the above engines with the transaxle or clutch assembly
bolted to either engine. These parts would be used for both
installations and their weights would obviously cancel.

Just wanted to share this information with you guys.

ToyJet.

Yeah - I heard the all-ali V8s actually improve the handling of Triumph Spitfires (not hard) because they weigh less than the CAST IRON 1.3 LITRE four banger that comes stock.

I am super suprised by it being lighter than a 6 though. I guess this is why the v8 people aren't all whining about the handling changes..... even if they are running iron engines, the 6 is pretty heavy.

Did you add the rad, hoses and water?

If not it might be break even.

I was surprised to find out that the 964 shop manual listed my 3.6 engine at a whopping 540lbs!!! I have to believe that's on the high side, but that's right from the Porsche factory service manual? Now I guess if I take that weight and subtract the A/C compressor/bracketry, power steering pump/bracketry, extra pulleys, air box, hulkamania exhaust system, dual mass(keyword) flywheel, it should bring it down a few lbs! But damn, it's still nearly twice the weight of the 4!!

I tell ya, when we pulled the motor out of my 914/6, I was a bit surprised how much heavier it was than a 4. It felt like twice as much.

An LS1 is not the same as a classic small block, and if I'm not mistaken the Vette LS1 has an aluminum block.

I have heard 550 lbs for the SBC for a long time from many sources.

Fiid, you've got me thinkin.. Is it the same mount as the engine your installing right now? For like say the person wanted to upgrade to that motor later on in life when daddy says that Im alowed to drive a street legal monster??

PM me some details.. Im just bench racing right now..

Andrew

It's a different, older engine. It ought to put out about 180 - 200 horse with a proper rebuild and tuning.

WHats up with that 911 motor you have in the classifieds?

Fiid.

Standard chebby small block with iron heads and light weight headers is about 525 lbs.
Aluminum intake manifold saves 25 lbs. Aluminum heads save 50 lbs. to get it down to 450 lbs.

3 liter six is 419 lbs according to the factory manual but I don't think that counts the muffler and I know it doesn't count the oil tank and associated hardware.

I am surprised by the posts that say a type 4 is under 300 lbs.
My estimate was 325 lbs. fully dressed with HEs and stock fuel injection.

Anyone actually put one on a scale to see?

My T4 with heads/clutch/flywheel(lightened) and carbs weighed ~400lbs when it was shipped...but that included the wooden box it was in...so I guess it was ~300lbs before the box.

I know that didn't help much ...but its all I got.

Tony

The 911 motor I parted. Got some good cash, but that went elsewhere.

I still have lots of parts from it, and most likely will go to ebay. Like Oil cooler.. im watching one on ebay right now..

PM me with the details.. Or email it to me..

Awesome JP....

anybody have the same tech info for the early aluminum block 1965-1967?

b

Hay, I stolt it off the bird list.....they worn't miss it.

I assume those weights are fully dressed.
My son and I picked up the 2.7 long block (to put it on the stand) quite easily......he's strong, but he only had half the weight. I am somewhat less strong
Me and 3 other guys picked up a sb Chebbie long block.....that was tougher & I was young.

I understand the early aluminum case is a fair amount heavier than the mag case...20-30 lbs....but don't quote me

Oh yea, that brings back memories. Years ago I had a chrysler hemi that I built up as a blown gas engine for a drag boat. Damn thing was close to 1000 pounds with everything bolted on. Talk about a lump. Good thing it had over 1100 hp to haul it's ass around.
