318 ideas..opinions please.

I don't see why you can't run what ever CR you want if your using racing gas and make sense that the domes and closed chambers will work if your custom fitting them. A 318 is just a smaller bore 340 it can make same Hp just a little higher in rpm, there's a guy on here that has custom forged piston and 2.96 crank for sale to make a 318 in 288 if you really want to spin it 10000+ rpms.
