Comp cam 20-600-4
Not a small base circle cam. I ran that in my sons ‘91 - W-150-4wheel drive truck. 4 spd manual-3.55’s on 28 inch tires. 10-1-360 engine with Edelbrock heads, RPM-600 AFB, headed-2-1/2 exhaust. Cam worked very well in the heavy truck.
It’s a bit large for a 318.
The Rhodes lifters would help a lot.
