Need bunches more information.

Fuel? Intake? Carb? Block? Rods? Crank? Exhaust?

I'm not familiar with the IMCA rules at all, so help me out a bit. But if you can run at least 110 octane fuel, I'd go with a flat top (4-6cc). That would give around 12.5. Play around with deck height and head gasket and you can get close to 13.

But the rest of the parts have to be able to stand up to it.
