anyone have suggestions for a 1992 4.3L TBI 'Z' code engine with a 5 speed for performance? it is a daily driver and has an exhaust on it, considering cam, not over the top but not too mild. would like to keep TBI, cat, and 4.3L.
suggestions on cam, lifters, etc. what do i gain, what do i lose, what does it cost, difficulty? it has to be budget friendly.
