With respect to your other comments about cooling, ditto. We do tend to beat this one to death. Use a big enough radiator (at least 2 ci. per HP with good ducting) and a big enough oil cooler. If your system over cools, pat yourself on the back andstart taping off the radiator until it's just right and install the smaller radiator.
