About to mod my virgin 318

That cam is 240* of duration @.050" and ground on a 108lsa. It will have no torque in a low compression 318. I would be looking at something in the 250-260 advertised range or 214-220 @.050" range. and run 323-355 gears with a 26" rear tire or 391-410 gears with a 28" tire. Get a good 11" converter. Make sure your distributor is curved for the bigger cam.

Buy a new cam, dont run a used one.
