Wiseco, Diamond, CP, JE, they all make a piston for that application, in many different compression ratios. They are a stocking piston for most of them.

Not enough compression, but thank anyways

I realize i can get a custom piston made:rolleyes:
I asked about shelf pistons for multiple reasons (for ex. price availability if extras needed,lead time etc)

I was kind of in the same boat as you and my advice after doing the research is have Diamond make a custom set for you. They sell a combustion chamber mold kit that you send in and they scan your combustion chamber so when they make your pistons the dome is contoured to the shape of your combustion chamber on your heads. Also you will need to do a mockup with a piston in the motor and your cam degreed in to get your piston to valve clearance so they know how deep to make the valve pockets. Lead time is around three weeks and you can buy individual pistons as needed. Most other piston companies I talked too have a minimum order of 4 pistons. That's why I went with Diamond.
