The pistons I am using are TRW Turbo pistons #L2441F.30 which have the dished heads.
The cam I have is a Weiand mild grind #8130 with an advertisted duration of 290 degrees on both th intake and exhaust, and a gross lift at the valve of .447 - inches on both intake and exhaust. Lobe seperation = 114 degrees, duration at .050 - inch of lift is 223 degrees. I know this might sound like a big cam, but, blowers have a tendency to tame a cam.

Remember I only want to run 6 to 7 pounds of boost.
Thanks for your help.
