Does my 451 have to small of a cam?

I will butt out. You guys are professional mechanics and i,m just a plumber who turns wrenches in his own garage who has no choice but to believe what he reads till the author steers him wrong. Never said a carb was a cure all but do know that in a lot of cases a soft top end will benefit from a bigger carb. Please listen to the pro,s and disregard what I posted. I,d hate to steer you wrong. Maybe the problem is nothing more than a low float setting but its hard to repair things theoretically.Wish you luck. Theres a lot of white papers that explain the theory of how things work where I quoted the carb sizing from. Its at Diamondback Racing Engines. Check it out. DD
