I have a 1989 5.0 that is heavily modded. I have heads, cam, intake, exhaust and AOD with a Bauman valve body and 3:73's. The only thing i havent done yet is computer work. Do all these parts even produce their potential with the stock computer commands? I sometimes think about the fact that the engine is controlled by a computer and not entirely by airflow like our ancestor cars and if the computer "knows" the parts are there; if it matters. i would like some recomandations on some chips. price is not a factor i just want quality. by the way i am running stock timing too.
