The only way to do the whole thing differently is to start over with either different combustion chamber volume or different piston crown volume to lower the static c.r. to where it will be pump gas compatible (around 9.0:1) with a short cam. The shorter cam will make power down lower and you won't have to run a high stall converter.

Bottom Line: Maybe you have spec'd the motor the way you want it. If that's the case, bolt it together and enjoy.
Tech,are using part Speed Pro #H345cp in your formula when you are figuring the comp. ratio?
