Help me find the right piston

[Scott S]

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,

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.

I really like ROSS pistons
