Help me find the right piston

I am building a 393 with a Scat crank and stock length rods. I am trying to pick the correct piston for 9.5-10 CR with 64cc iron World Windsor heads. The cam won't be huge so valve clearance should not be a problem. Forged pistons preferred.

Thanks,

Scott S

I'm not sure about the correct piston for you application but my engine builder uses JE forged pistons in almost all of his engines.

Scott,
I'm building a 393 as we speak.
The KB 192 hyperuetectic with a 12cc dish will give you 10.2 to 1.
That's what I installed with the World Victor Sr. 64cc heads.
If you want less compression you'll have to go with more dish in the piston.

<http://www.kb-silvolite.com/calc.phtml> is very easy to use for calculating compression ratios.

I don't see the need for forged pistons, but that's just me.
