Pistons for 393w
I'm building a 393w and am in need of some pistons with about a 19 or 20cc dish (I think). I need 302 style pistons as I am using the stock 5.956 351w rods. I will be using World Products Windsor Sr. heads with 64cc chambers and would like to have a compression ratio of about 9:1. I would like to use some fairly inexpensive forged pistons if possible. Any suggestions?

I build my 393 with KB pistons. I can find the number if you like. They have one with a 22cc dish. More importantly, though, you need to figure out you Dynamic Compression Ratio based on your mechanical CR and you cam timing. I build mine for a work truck. I had to use 69cc heads and CNC the piston to make it run on 87 with a short duration cam. Do your homework and it should come out fine.
