Yea it was an anniversary edition

What you guys are talking about is the 1989 Pontiac Firebird TTA or Turbo Trans Am. Only 1500 were built and are still fetching $10K+++. The drivetrain was a G/N short block, turbo, & exhaust system. The G/N heads were NOT used because, believe it or not, they were too wide to fit between the shock towers! Solution? Use FWD 3800 heads! And as a added bonus, the FWD heads actually flowed BETTER than the RWD heads.

Now that is some good info...


i'm working on a 3.8/3800 hybrid for a buddies 84 reegal (converting to EFI) and wasn't sure if the FWD heads would work on the RWD block.

Now.. if i could work out a crankshaft trigger and a few other things i could get this project rolling.

3800 heads DO NOT interchange with the 3.8 block. Otherwise all the 3800 guys would have been using the aftermarket aluminum 3.8 Buick head a long time ago

[3XTurboAgain]

are all 3800s chevy? i'd keep the 3.4, I'd throw aluminum 3x00 topend on there , 10.? /1 compression, huge cam/valve springs, tune it, RWD headers, that would be way cheaper than all this swapping stuff.

3800's are based on the original Buick 3.8L but it uses the GM metric transmission bellhousing pattern. They are not Chevy or Buick there is no such thing as brand engines anymore. They are all just GM engines. Yes some are used exclusively in certain brands like the Northstar V8 but they are not built by Cadillac.

[IanSzgatti]

maybe he used "bolt right in" loosely. it's like when i told my boss the 3500 would go into the malibu, he said no it won't. boy do i wanna slap him

Just steal forcedfirebirds ideas .

^^^ WERD.
and they were a buick design to begin with, but then corporate got their dirty hands on them and now they are all global design. i dont think much works from the 3.8 to the 3800 really

jerk it out & put a dohc in it-& turbo that-i figure you could take a v8 cam with that setup with only about 3500-4k (you dont have to gain nearly as much power)-160 to 210 u only have to gain 75 hp rather than 125

The 3.4 should get the 3400 top end treatment, then supercharge it with a Vortech or Powerdyne. You can turbo charge it also.

The 4.3 is essentualy a 350 with 2 less cylinders. You'll need a longer drive shaft at the least and just use a commen 350 automatic or 5spd. Using the Vortech requires costume intake manifold if going boost. The internal injector setups are a joke and fire hazard. The non-vortech heads are a real restriction. Use early 80s 229ci (underbored 4.3, essentialy a 305 with two less cylinders) heads. They have smaller valves but flow way more than the 4.3s even after porting. Plus you can use a carb for blow thrugh. Vortech can't use non vortech manifolds. You can use 350 forged pistons on a 4.3, but not the rods. But there are forged rods for the 4.3.

[gectek]

brodix also makes heads for the 4.3 and GM also makes a bowtie 4.3 block...but thats all carbbed style suff...you can use the bordix heads with the TBI intake iirc, but if you want to use vortec heads, then you have to get the intake or heads machined to accept the diff angle. but dont use the 4.3. just go 3.4

F-bodys are muscle cars, and they need a v8. I really cant stand v6 muscle cars(other than gnx). There slow and the owners are usually overconfident, throwing the name camaro and firebird around like its some big authority, even though my pos beretta will take it in the quarter.

I just dont have ANY respect for v6 f-bodies, mustangs, chargers, etc...

F bodies are cooler then L bodies, even with a V6
