I looked into this a few years back - tossing up the idea of 3.0 24v vs V8 for my GTV.
I'm sure I found some stuff on the GTV8s about using Monty engines but at 3 litres.
I'll have to see if I can dig it out.
A couple of years ago I also thought about doing this, great project, but when I spoke to Dawie from Glenwood who had done this, my plan changed. You have to move the cross member with the steering rack down. This is apart from the mounting fabrication. Rear bell housing fits though, but the alignment with its mounting has to change....just allot of work for marginal returns.... Fit a well prepped 12v or a 24v and you will probably get better power and better torque curve and you wont be messing with the steering geometry too much

I have always wondered about dropping a LS1 (or family) smallblock into a GTV6. I am sure it can be done in front, but have no idea how to get the power to the back and put it down without a major problem. Of course, the obvious solution would be a Vette rear setup but that would surely take some major surgery.

if one had to go chevy of all things...why ppl pick it i have no clue...a mopar small block is actualy an easyer swap into most positons
if it was me i see only 3 options
trans up front and make a mount for a IRS senter cetion from a vette or jag mounted from the stock transaxle position......use a vette or cobra transaxle(probably the easyest and most expensive to get your hands on)
ive hear it time and time again...the supra 5 and 6 spd can handle STUPID amounts of HP before it fails...and there easy to get your hands on....so me id use a supra trans and the IRS diff houseing and fab a mount to mount it right where the alfa transaxle is...i see this as the easyest cheepest way out and theres pretty much an adapter to use that supra 5/6 spd to ANY engine out there

LS1 chevy is a very good engine. 6 bolt bottom end. Second option would be a cobra (new) engine. What mopar engine are you referring to?sh0rtlife wrote:if one had to go chevy of all things...why ppl pick it i have no clue...a mopar small block is actualy an easyer swap into most positons

I almost certain the supra box is a getrag.

I think it's best to keep an Alfa V6 in there.
The Montreal V8 may be a great engine, but parts for it are expensive and relatively tough to find. Have you checked the price on a Montreal distributor cap and rotor lately?
American V8s offer a tremendous amount of power for a give size and weight. By size I mean the physical size of the enigne, not the displacement. They also offer relatively low cost. The problem starts with everything aft of the engine, and I mean nearly everything. The body structure, driveshaft, transaxle, rear suspension mounts, rear brakes, etc. The cost and amount of work needed to do this would be massive, and when you are done you won't really have a GTV6 anymore. You will have a V8 powered garage engineered car that looks like a GTV6. It would make far more sense to drop in a hot Alfa V6 AND buy a Corvette. That combination would probably cost you less.
Regarding the Chevy vs Ford vs Mopar small blocks, the classic versions of these engines are all very similar. The Chevy offers the greatest amount of aftermarket parts and the lowest cost. The Ford and Mopar engines are every bit as good in all other respects.
The jury is still out on the newer pushrod V8s. A G.M. LS2 vs a Mopar 6.1 Hemi is a pretty good match up. Chryslers basic design philosophy has always been to build a motor as good or better than the other guys, use cheaper components in other areas and sell the cars for less.

Hi,
I recall seeing a gtv6 fitted with a small block Chev motor about 10+ years ago in Pretoria, South Africa. I think it still had the Alfa driveline,suspension and brakes. The owner used to work at BMW. At that time the E36 BMW M3 just came out and this would destroy them around the Gerotek highspeed oval.
The car impressed a lot of people, but the Alfisti didn't like it because he basterdized the car by putting this engine into it.

purists always get pissy and pop up like pimples when stuff like this springs up
i think the only GM engine i would consider would be an old buick v8(the old aluminum block)
haveing a chev 350 mopar 318 and a ford 302 all on the floor in my shop right now for several years i can say this...out of the bunch the mopar engine has a lower overall height and the mounts are at the very front of the motor makeing it an easyer swap into most cars...its simply overlooked for favor of the 350 since there cheep
my "dream" way to v8 front engine transaxle rear would be to take the tail shaft section off a supra box and direct mount the diff section to the transmission...this kind of setup could fit into an alfa with ease
so whats the new 8C engine look like...wonder if we could shoehorn one into an old fetta/gtv6 and remove all of the extra "garbage" off the engine

Theunis how's that rebuild of yours coming along boet ?
I too, recall that GTV with the V8 motor.Had a chap who owned a 2 litre turbo GTV who also worked for BMW at around the same time.Neither of them were to popular with the BMW brigade.
Ah that pic reminds me of a classic photo in Autosport with that GTV tucked in behind two Porsche 935's.Awsome photo.
Seriously though it would be fantastic to obtain one of these rare V8 GTV's and preserve it for posterity sake.
Shortlife,I wouldn't be too surprised if Alfa brings out a 'new' GTV with the 8C engine sometime in the near future,hopefully rear wheel drive.

if its not RWD its not a gtv...am i right????
its a shame alfa left the states...cause right now im sure we could find a few totaled out 8c's to snag an engine and wireing from at a wrecker.....tell me that swap wouldnt be fun as all hell
even if thats a tubber up there that thing is SEXY!!!!!...automotive porn i say!
