4 speed ka-booom !

If you do not have a dyno sheet, you will have to zero in on the shift points the old fashioned way, by running shift loops. The points that make the highest mph are the winners. Alternatively you can install one of those accelerometers on the windshield and generate your own dyno sheet. Then knowing your tranny ratios you can graph the ratios against the hp curve and derive the probable shift points. Then you get to prove it with the trap mph again. But it will get you really close right out of the gate and save your engine all those loops. A little short shifting with a small cam is usually better than staying in gear a lil too long, with the possible exception of actually running through the traps.Here you could be a few hundred rpm over the peak, cuz small-cam engines don't usually have a well-defined hp peak. For that you would need a tight LDA, and to really take advantage of the tight LDA, it would also want a transmission with tight rpm drops, like a 5 speed. The 292/509(.543 with 1.6 arms) cam I had was like that. It was a 108LDA cam, and the hp peak was quite pronounced. A stock 340 cam is a 114LDA, and is very mellow. The 110LDA cam I now have, is mellow enough, but it's only a 232*@050 cam. With 1.6 rockers, it does, however, have a published lift of .549. I can shift it almost anywhere and find plenty enough torque for street fun.
