I figured i would post this here since the 5.0 guys mainly focus on 302's. I bought my 83 GT from an old friend. It's powered by a 1966 289 block with 302 heads. All the internals are new. Forged rods and pistons etc...
When my friend put the motor together he must have done something wrong. When i hook up a timing light to the lead plug wire the timing marks are not visible. As you start advancing they come into view. Once it reaches TDC it's idling very rough with some spark knock. Advancing beyond the TDC mark at all and the car will hardly run, and barely turn over after you shut it down. For the engine to run smooth the timing is way retarded. This is according to the timing marks/pointer. Obviously the timing pointer/marks are way off but why??? I thought some of you classic buffs might have some insight for me.
