Shift points, I did 5700 rpm first run, 6000 rpm 2nd run, and was going to try 5500 on a third run but the rain started and did not stop. So as of now I don't know what is best. If you are correct and 5000 rpm is the limit, I will need to lower the rpm. Those headers were on the engine when I purchased the car many years ago, still in good shape. I welded a 3 inch exhaust system with homemade x pipe. I'd like to redo it (moving the mufflers and tailpipes ) with something similar to what you have, prostreet.
