Thanks guys. I will post my results here when the snow falls encase others want to know. Hard to get any solid info on the little 6's. Time sure is passing by!
What is your squish? What octane are you running 110, 112 or 116?I have a 97 Zrt 600 that I’ve built for snow drags. The heads are cut down and I only run race gas. I tried a 5 degree keyway and the motor is flat and would of rev higher than 8900 rpm. Has anyone tried the 1-3.75 degree keys and found one key worked noticeably better than another?
