I have a timing problem. I installed an older MSD mechanical advance distributor with a Blaster 2 coil and 6A box in my fresh rebuilt 327. It runs well but I can't seem to get the timing near spec (8* BTDC), with the gun. It wants to stall as I approach the top of the timing tab! The distributor was new straight from MSD so it has the factory springs etc.. in the set up. I've never modified it. What would cause this? Could the dist. be a tooth off? Should I play with the advance curve (springs & bushings)? I'm at a loss. I can put it on a dyno for $125/hr but want to try it myself 1st. Wally Booth built my short block and says it should run at the factory timing spec even with the bigger cam. I'm sure he degreed it properly, Wally is a legend (Booth-Aarons). It runs pretty well but it is a bit too advanced for easy starts. Any advice would be great! Thanks.
