with the stock cam and engine by redline the car is out of its power band... the only gear i take it to redline is first so that when i shift into second i dont spin. the rest of the gears i shift at 5200-5500 depending on how it feels. the first time i went to the track i didnt know this and when i went back i shaved over .3 off my time just by adjusting shift points.

+1 5200-5500 rpm anything else is a waste of time

when i used to shift that high it did nothing, after going to the track and seeing results after shifting lower i keep it around there. then again all these cars are different so you just have to try different things and see what works best.

You're a GT he's not. 4v's have different power band range than 2v. 2v's are tourqier down low than 4v's And the 4v's build more power at higher RPM's. If he had a higher rev limiter I would tell him to shift at 6200. But to be safe on the stock block and so his engine doesn't cut out while racing 5900 is cool.

yeah, I just looked it up again 97 cobra stock 249.6hp @5700 rpm's so why should he shift at 5900-6200 rpm's????? listen OP you want to shift right at or right b4 you peak NOT after peak. so I stand by my 5500 rpm shift point!!
