Why are 318's low HP and torque?

sheeot. That's kinda close to what I'm doin with my truck motor and I'm gonna leave it in there. lol

Yup.

Here's what I did to mine. Comp HE268H cam, 1 5/8" headers, Weiand 8007 intake, opened up the port entrance on the heads to match the intake (gasket match) and a Summit 600cfm carb. I also run a 3.55 suregrip 8 3/4 rear.

It runs well for what it is and will get me by until I get my new engine built.
