Does my 451 have to small of a cam?
There's one big assed problem, try a 3200 to 3500 stall, cam dependent. What's your initial timing set at, what's your total not including vacuum (plug it if ya got it) and what RPM are you at when you're at full advance. I'd be looking at 12 initial, total 36 and all in at 2200 RPM. Also check that carb out good it could be as simple as the secondaries aren't opening.
