I'm an 18 year old still in college, and recently i bought a 1987 Firebird (V6 2.8) and i was wondering if there is anyone out there or anyone that would know if a swap with a 427 is possible. I know I could do a 350, but I know someone who is getting rid of a 427. If it is possible, I'd like to do it...someone enlighten me please.

Might want to post this up in the small block/big block section for better feedback. There are quite a few 4th gens with Gen I SBC and big blocks conversions on here, and I'm sure you can pick up a few tips on what to look for.

I'm no expert on engine swaps, but I know that almost everything needs to be replaced. Pretty much the only thing underneath the hood that can stay is the battery it's that much work :lol:

Well, the factory once put 454 and 455 in the old style Pont and Chevs. Measure between the strut towers. See if a 427 fits.

I always felt a stroked 3.8 turbo would just be a blast and a real sleeper.

I remember seeing a old article in Hot Rod of a white 3rd Gen GM put a 454 and a 6 speed from a vette in it if I recall right it took them ALOT of work to put it.

i saw an article like that also it was the one when he did the steps in like 10 years and now its running like 11s lol but i think that might have been a 350.


well as for your swap its gonna be rough... im doing the 350 swap and its confusing me already...stupid wires.....going carb........but yeah i think u would have to replace everything under the hood and the rest of the drive line and shocks and................some more
