cam upgrade worth it?
Another member on here picked up .6 E.T. and 8mph with a swap from a LS6 cam to one of our custom grinds as well.
These are but few of many who have gained power, e.t. and MPH with our turbo camshafts over stock.
i used a 99 4.8 totally stock and just valvesprings
car went 11.0 @ 126 first pass with a so so 60ft
on3 76mm and 18psi 12deg timing pumpgas
installed a isky triple 12 cam from JFR and went back to the track
did not change anything but minor fueling fixes
10.72 @ 136, i picked up 10 mph! from a small turbo cam
that is a significant amount of power
