i have a stock turbo350 tranny, do i need a stall or kit becuase i already plan to put a floor shift kit in it.
also im thinking very hard about buying a simple nitrous system like zex or something just so if i wanna go to the track or something.
anyone suggest any kind of piston i know you have to use forged but just asking if anyone has a fav. brand or type they use.
also i plan on buying roller rockers, hardened rods, and a new crank. with the crank should i stay stock 350 or up it to a 383 stroker.
thanks everyone
