318 rebuild for turbocharging

My mistake. I read you wanted to swap over the pistons. You meant heads. Which is totally acceptable.

With a 318 stroker, you're going to increase the compression beyond boost safe levels I'd imagine. Maybe they give you piston options to lower it, I don't know. I honestly don't see the point of stroking a 318 just to add boost later on. For example, I set a goal for my car to make 450 ish torque. I had the option of a 360 mag but it was a little harder to find than a 318. To make the same power goal in a 318 vs 360 I'd just have to add a little more boost. whatever the engine is, I'd figure I'd have to limit boost with the wastegate anyways. Some guys run an oem short block to 16+ psi. I'd never need to go that high. It's either 13 lbs with a 318 or 11 with a 360. My transmission, axle, and unibody strength determined my realistic power limit, not my engine.

If you go stroker, I wouldn't bother adding boost. But I'm not here to spend your money.
