I have a 304 that has been completely rebuilt with a very mild rv cam. I am currently running a Holley 4412S 500cfm carb. It seems to be too much flow for my motor. I am thinking of going back to a stock carb. Anyone else had this problem and what carbs are you running on your all's 304's?
I run the Holley 4776, 600 cfm, double pumper on my 304 and 360, it runs great. It may not be too much flow that is causing your problems, rather, it may be a weak ignition. -joe[addsig]
