What size turbo (single) or turbos (twin) would be big enough to sufficiently feed a 454??

 

Depends on the mods to the 454, but a single 70mm "new" series inducer should do it. A pair of T4s would work as twins.

 

iam getting ready to put a 383 i have in the shop. eagle bottom end 350 bored 30 over 12 cc pistons 400 crank 234/234 cam duration 64cc head tpi with twin t4's she aut to be a beast o yeah if ur goin big block i would go with a super charger unless u have the money to make that big block wine like a snappy sb

 

Why go with an SC on the big block when a pair of $600 turbos can flow enough air for 2000 BHP?

 

well 2000 horsepower seems a little too much for what i'm lookin for, i'm hoping for maybe something around 700-800 hp. i want it to be somewhat streetable so i can have fun with it whenever i want, not just a track car.
