I recently replaced a lot of stuff in my 1972 chevy 350 motor, we took the crank out to replace the rear main seal(its a two piece, and we couldnt get it out with just tranny out so wee took the whole motor and crank out) Anyway, after putting everything back together she runs.I have the idle set right at TDC, i do not know what it is supposed to be set at. It runs and idles fine there but the motor sometimes stutters and backfires when under a load in 3d and 4th gear, when under about 1200 rpm.I think the timing is the problem, does anyone know what the timing for a 72 chevy 350 is supposed to be set at? or it could be soemthing else
I think it is supposed to be 6-8 degrees, before TDC, depending on whether it's a manual, or auto.I always set mine at 8 degrees, regardless.

already found it online, found a bunch of sites that said 8, and a bunch that said anywhere between 6-10... I set it at 8 and it runs perfect. no more problems, thanks eitherway
