5.9L Magnum recipe...

Nice tip about Brewers, I'll have to remember that.

I don't run a computer but, the RPM heads should be well preped, use the rpm intake, 1-3/4 headers would be my choice size into a 2-1/2 exhaust, cam size of [email protected] with as much lift as possible. Use the KB slugs. Use a 750 carb.

This should easily crest 400HP.
