460 dyno charts dyno tuning at its best
Here is a dyno chart of of the difference the high lift cams made on the 460. The stock cams had more torque below 7000 and also peaked earlier. The result of the high lift was the same torque number but 1000rpm later and there was a top end hit of 3 hp more.
Both engines had were identical with an open fmf system the only difference was one had stock cams the other the high lift exhaust.

Porting from a year ago, I was unaware that your porting had a shelf life Wistech!!!
I was looking at your chart and boy is it all over the place but you still got the good numbers.

As porting improves every year the older the porting the less the output.
As you can see only 2 engines were near each other because they were built almost the same. The cams ,cam timing and exhaust were all different so the results were very different.
