If they can only get so much fuel thru the motor, it will only make so much power.Leave the 3.20 gear in em, and they wont over rev. Clutches would be 3 or 4 disc, not 5 or 6. They can run all the other stuff they have, short of camshafts. Heads might be too big, but after you wear out what you have, work on a new head. Digger rules would mirror FC.
They were loud and nasty in the 70's and early 80's, but a good deal slower, for a while anyway.
Kenny, I'm obviously not a fuel crew chief either, but why make all of those expensive changes. As I proposed in my earlier post, have MSD reprogram the already mandatory Rev Limiter to take away timing at a lower RPM than the current 8200 - 8300; that will force the crew chiefs to flow less fuel at that point, and consequently, make less power. If a 300 RPM reduction will slow them enough, so be it; if 1000 RPM is necessary, then so be it. In my opinion it would be the most cost effective way to accomplish the goal of slowing the fuel cars to about 300 MPH which is where the NHRA wants them to be.
