Ya got good valve springs in there? Wind that beeotch up! I'm shifting at 6800. I understand I have a bit more motor than you, but you're setup should be more than capable of reaching 6500 or so. The cam is only "good" to 6000, but your entire engine might like it better at 6500 instead of 5500. Remember the engine is a system, and everybody gotta play nice together. Heads and intake may take over where the cam leaves off.

Keep us posted!

Yep...all new valve springs. Based on trying different shift points, it seems to like to be shifted at 5800...any more or less and E.T drops off. Going through the traps in 3rd, at 5500rpms, I can tell the engine is running out of steam.
My 60' sucks...even with slicks so now I'm leaning towards the converter being the culprit. If I can drop my 60' by .2, I will be in the mid 12's.....make sense?
