70 big block hp exhaust manifolds
What determined which engines got the hp exhaust manifolds. I've been to a lot of shows and i see some cars with hp exhaust manifolds and some without. Is it just the owners choice or did only certain engines get the hp manifolds. Thanks, my car is an "n" code and was wonder what the correct manifolds should be.

N code is a 383 magnum so you should have the highrise HP manifolds , there is a L code 383 2 bbl & an M code 383 4bbl non magnum engines , all magnums , Super commandos & TNTs had the Hp manifolds
