I'm currently building a frame up resto-rod 71' firebird, and am planning to throw in a fairly aggresive chevy 454. But I'm not sure whether I should turn to the th400 tranny or the th700R4? the th700R4 deos have the overdrive so that would be nice,I also heard that the first gear is like 25% lower than that of a th400. which would help that big engines low end. but I just don't know much about the 700r4, or whether it would even take 550+ horses. pleaz help
Why does interests in your profile say trans-am :screwy:
In his intro thread it also said Firebird :laughing:
EDIT: His dad had a Trans Am though lol
Isn't a Trans-Am a Firebird??
Firebirds and trans-ams are the exact same! All a trans-am is, is a firebird with a shaker hood and fender flares. and I've turned my firebird into a Trans Am by doing the proper add ons. but good observations though. :clap:
Now is anybody going to answer my question?
someone already answered your question in one of the other hundreds of
places you posted the same question. this is not a a way to endear yourself
btw, the trans am had different base suspensions, different base engines, etc than the firebird. you make the trans am sound like a "tuner" version of the firebird when it's really much more...
in response to a question that you posted in even another place: you can probably get an adapter kit to mate a bop trans w/ a 454, but i don't know how reliable that would be w/ 550hp. who knows? it may be fine... a buick olds, or pontiac 455 would bolt to it, though. i would choose one of them, myself...:thumbs:
ive got a 400 buick trans mounted up to my 350 in one of my demo cars motors w a custom cut adapter plate. its held up pretty well.
