Inliners International Forums General Discussion Hi Performance Lookjing for 300 Hp What can I do?

For a 250 engine, the 307 Chevy pistons interchange with these engines. The 327 can work, but you have to bore the engine out to 4" to use these, and that is getting the cylinders pretty thin. The compression will depend on whether you use a dish, flat top or dome piston. Good results can be had by turbocharging either the 250 or 292.
