440 timing advance
The 440 in my car has never ran the way I think it should. I bought the car in 1989 w/ a noisy #matching 383. By 92 I was tiried of changing things on 440 to make it faster so I had a roller motor built. Started family and car went unfinished until now. I'm trying to get the timing set but something seems wrong. The gun shows 36 deg. at idle! (1000 rpm) Mech. adv. starts at 1200 and is all in by 2000 rpm. The guy that built the motor put a white mark on the damper at 36 deg. Would someone install the cam that far advanced? Car runs good at low rpm(1000-3500) but breaks up above that. I'm using a mallory unilite. This motor was built from oil pan to carb ready to run. The only thing I'm not sure of is the cam spec. It's a crower street roller (w/ .624 lift and between 280 - 290 dur. I think ?) Do I need to tear it down and slap a deg. wheel on it or does this make sense to someone?
