You're right, I think the total is actually at 42. Don't know what rpm it is at when it reaches though since I didn't have another person looking at the tach. (Probably need to put some lighter spring in when I have time) She idles fine and I made some wide open passes shifting at 5000 and she is not pinging. Should I still be worrying about it? The motor has a lot of cam to it and it runs on the cool side no matter how hard I run it so I'm thinking that is whats allowing me to run so much timing. Does that sound about right? Thanks again for the help.
