Hi tmm ! fresh commando rebuild from last summer Mike . about 2000 miles on it already. time to let her stretch her legs some. lol I only took it up to 5900 rpms so far. I did call isky today , Ron said if you have a good bottom end .. take it up gradually in increments to 6400 rpms where the cam is in it's glory . said the cam is just coming alive in the upper rpm band. I could be giving up considerable hp stopping at 5900.
