Pump Gas RACE motor

No E-85 on the Island. Bummer.

Tim, Lowest possible ratio? For it to perform as built maybe. Your in a catch 22 on the engine. Perform as intended or a sacrifice in ratio.

Does anybody know if MoPar or other place make the head shim. I grabed one for my 360 some time back. The steel shim MoPar made for the small block that was .060 thick I think it was. Then add a gasket to it.
