ok, so i have a 89 notch that was a 4 banger, but was converted over with ALL the v8 parts from a wrecked 88 gt with sd. The motor is 100pct stock, and has 1k on it from a freshening yrs ago. it has sat for about the last 4 yrs. i am looking to make a streetable notch. 350 or 400 hp. i plan on going with 3.73 gears, a tremec, redoing all the suspension, etc....what i am unsure on is the best engine components to get to 400hp? i would like to achieve this with out a charger or the bottle. i also am wondering if i can and should use this stock bottom end? if so what intake, head, and cam combo is gonna be the best for my goal? injectors, and mass air meter sizes as well? the car is speed density as well so i know i must convert that as well. i want to be able to smoke most street cars i encounter, but still maintain driveability, and be reliable as well. thanks for the help fellas.
