Ron,
700hp is doable with a net 305-310 cfm (through the plenum, TB, and airhorn). That takes at least 335-340 @ .450 lift just through the heads.

Your LPE's are probably close to that.

These are really nice cams, and I'm having second thoughts about letting them go. One-of-a-kind, for sure. I wish Steve wouldn't have closed his business (Integral Cams). His work was first rate, and his knowledge of metallurgy and spring stresses was tremendous.

As for my next version... no, not 8000. Not with a 4" stroke. 5000 fpm (7500 rpm) is the absolute limit I feel comfortable with for an endurance build. I intend to make peak power at 7300-7400 rpm.
