I don't have cams, but I did do my gears. They're 4.10s, and I'm S/C too.
My gears do not whine. They might whine if you install them poorly I suppose. We installed 4.11s on my brother's Trans
Am, and they didn't whine either. They just completely exploded after a summer of much abuse.
I can spin like hell in 1st and 2nd (BFG street tires) and I haven't purposely tried in 3rd, but I think some drag radials would help that out a lot.
I know conventional wisdom says 4.10s are
with a S/C, but I sure as hell like mine. The thing's a rocket cruising around 30 in second gear and you let her eat. You just gotta know how much gas will make you spin, and how much will allow you to hook up. I really can't imagine that with 3.73s you couldn't just lunch tires all day long either.
To each his own...I don't care much about going 150 mph, nor am I a pro drag racer, so...4.10s
