Like I said, just throwing it out there....food for thought as it were.
I did test at 300 RPM/sec, not much difference in power output. The fast F/SA Buicks 315/330 HP run a 4.30 gear and turn 6600 RPM in the lights, and run 10.80s @ 450 elevation. Its important to note the 315/330 is a whole different animal than Jason Lines C/SA combination.
