The way it sits now its running thru a 3" exhaust system. As for RPM range it goes to 7k without blinking an eye. I havent had it above that yet but it still has more to go.

Take .575 and divide it by 1.5 = .383
Now multiply .383 by 1.6 = .613
I believe it adds some duration, but I honestly don't know if it's enough to even notice. I've always been under the belief it might be a degree or 2.
Take your lift and divide by 1.5 which is .383, so you have a .383 lobe.
Take your .383 lobe and multiply that by 1.6 and your new lift would be .613.
I’m not sure of how to exactly figure how much more duration you’ll get, but the math smart guy’s probably can. I say you’ll pick up 2 degrees at .050 but don’t hold me to that.
Or if you are lazy like me....... divide the lift by 15 and multiply it by 16, saves a couple clicks for the decimal points.
100% true. But I’m a weirdo so when calculating compression ratio and stuff like that I work to the third digit!!! So a couple of decimal points is just a bink bink on the keypad for my sausage fingers.
