What size throttle body is best for a stocker lt1? are aftermarkets legal? Do certain brand fuel injectors make more power than others? Thanks

Whatever NHRA mandates as legal. No. Yes, depends on what your
doing with your tune. J.R.

No, aftermarket throttle bodies are not legal. Original GM, factory LT1 throttle bodies are required in NHRA Stock and Super Stock.

I know of a fast LT1 Stocker with the original injectors. Would not be my choice, but he is fast.
