Whew....Fishy? I can see that cam being worth way north of 60 rwhp vs a stock cam under a blower. 227 on the intake is pretty healthy. Worth the time, effort, and/or money to do the swap. Unlike the LS9 cam which probably isn't
Kind of silly, in my book, to go to all of the trouble of a cam swap just to slide in an LS9 cam.
If not wanting to change the valve springs is the reason for using the LS9 cam, understand that there are plenty of better choices (custom grinds) that don't mandate a spring change.
