I've been wondering this for a long time. I am running a 600cfm eddy carb right now and my motor has some good performance to it. But then I got my old man who has his 85 dodge pick up, 360 bare bones stock. Only thing not stock is intake and we took off all the emissions. He's putting a 750cfm carb on his bare bones stock truck but when I want to put a 750 holley on my car, he says it's too much carb... I'm lost cause my engine is making almost 2 1/2 times more hp than that truck. He went and kanked my carb off my malibu so he could "test" the truck because he has been having trouble with the thermoquad he bought for it. So how should I know what carb to use???
