Jimmy, thanks a ton for the detailed info, just what I need. Even though i'm not building a 500-600hp jimmy the 'free' hp is the best kind at whatever level you are running. I used to have a big sheet of that thick diamond screen for making pan screens but it is gone now, so I'll have to serach for more. Have you fabricated shields to mount in your block to keep drainback oil from landing on your cam ?
