ZO6 shift point question. What do you shift at ???
I have a LS7 motor in my 32 truck. I have headers, custom grind cam motion cam. Trunnion up grade. The cam size is between a BTR stage 3 and a BTR stage 4. 240/252, 654/ 640 113 +3. My heads have been fixed by WCCH. But I did not mill them. And I have a tune. My rev limiter is set at 7500. I was shifting at 6300RPMs before the new cam, and trunnion up grade. I run a tb400 manual valve body. So I can shift where I want to. I am going to try a higher shift point. SO I WAS WONDERING WHAT YOU GUYS SHIFT AT ? At the track. Thanks Robert

Your duration #'s with the 113lsa should be able to shift somewhere between 7350-7600 or more, I have a lot less cam & shift at 6900. Your 3 speed setup will like being shifted at a higher rpm point than a 4 or 5 speed would. What you want is the highest average HP in each gear range. I feel that I didn't word or explain that well.
