Usable power for the street?

273-106.9326 with a 1.78 valve
318-103.4599 with a 1.78 valve
340-104.8796 with a 2.02 valve
360-101.6965 with a 1.88 valve
408-100.7280 with a 2.055 valve

I always round down and make sure I have enough duration to carry the RPM I want.

You can’t use these numbers if you want a flat curve after peak HP. You have to open the LSA up for that.
