What's the compression height for a 360 magnum as buying pistons

Ah OK, I used the wrong combustion chamber volume; your numbers are no doubt right. I now get 8.32 with .050" thick head gaskets.

How much boost are you planning? And will this be ECU controlled fuel injection or carbed?

No reason you cannot grind out some cc's from the chambers, and maybe use tulip-headed valves, all the get more volume. I've ground out 8 cc's from chambers before to set SCR with the desired pistons. (But not SBM's so I can't advise on where the thin spots may be).

Thanks for your reply, Your numbers are correct . I am using a .040 gasket but can go thicker. I've been running this engine for a couple of years on 15 PSI with a static compression of 9.3. I'm around 645hp at the wheels on the stock old pistons and one finally let go. It was a great setup but I thought while I'm going forged pistons I will try and drop the compression of it in case I want to go up to 20 psi. I wasn't sure if I could run 20 psi on 9.3 compression. these pistons would give me the compression I won't but I just wasn't sure about the stroker comment and the brand
