What cam?
like dgc333 said i also think that 750 is a little to much for a 318 used to drive a 318 with some cheap headers, a 600cfm edelbrock a edelbrock performer manifold and a compcams cam cant remeber wich one think it had 268degres of intake duration, it ran real good but the cam was a litle to big and didnt have so much torque would probably go for the XE262 like moper and dgc333 sugest if i did it again!
