So how many cubes are you building this monster to?? Are you installing a vacuum pump on the motor to help control the windage?

Daryl: It is an Donovan 10.2" deck Donovan aluminum 620" EFI pump gas motor. We did not put a vacuum pump on it originally, the builder is changing the screen baffle in the pan, adding drainage and pressure equalizing lines from the ends of the heads to the pan and a pan scraper. The vacuum pump will come if all the other things do not fix the issue. He has it much better than when it was first on the dyno. If I had to do it again, I would have dry sumped it
