Making power out of the 318

Depending on the chamber volume and what they actually measure at, you could use kb399’s. They’re domed and could put your compression up higher where it won’t be a lazy low compression combo. What axle, gears and tire size does your car have? That has to be considered for your cam. Stall of converter?
So currently I have a slant six so i will be getting a new trans i have a 8 1/4 with 3.21s and i will be getting a new converter with the correct stall for the cam that I get
