Hi Guys, I currently have a smaller carbeurator on my roadrunner, it is a holly with vacume secondaries...my neighbor has a big 750 edelbrock (I think with mechanical secondaries) he wants to sell it to me for $100.00 I want more power in my 440(it sounds and goes like a damn 318!) Anyways im not sure if id be wasting time and money switching carbs...will it make much of a diffrence without putting in a big cam and changing compression?
