Most LS6s and LSx have peak HP is 6200-6250 rpms

Depending on the cam put in that peak may go up slightly to 63-6400

peak tq at 44-4500 +/-

changing your gearing to keep your engine in the optimal RPM sweet spot is a good idea too.

John Heinricy said the optimum shift point for a stock LS6 is "one rpm short of the rev limiter"......

According the the torque multiplication the shift points for a stock C5Z LS6/M12 tranny are 7200 rpm for 1-2, 2-3 and 3-4 and 6400 for 4-5.

If you shift sooner you are actually giving up some "pull".

This seems to work out for Buttermore in his T1 car.

actually on an LS6, the ideal shift point is about 400rpm ABOVE the rev limiter!
