[fire120ball]

Too start out this is what I know, I have a 350 with forged pistons, am not aware of the cam size etc, I have edelbrock aluminum heads, am unaware of which heads exactly with the seriel number being on the back side of them, I have edelbrock performer aluminum intake, normal rockers, stock plugs/wires, hooker headers, and a carb spacer, and a 670 Holley Carb.

I want some great torque with hp to be right there, I can do all the work myself, which I have done before but I am 18 am not knowledgeable enough in what cam size etc to throw in and if I should start from a new/old block and go 383 or what. I have a very solid job and want to start throwing some cash at my baby
