6.0,awd and a 65e.
ive got 20k on that combo in my c3 with a whipple on it with no problems but i dont flog it.
not even any w.o.t. 2-3 shifts and never an aggressive 3-4 shift.
mines still got the whippletronics on it so it aint right or i probly would flog it more.(it wants to ping sometimes if im not careful).
the stock shifts arent firm enough to handle high power shifting.just use common sense if you go stock for awhile.remember if its not shifting crisp its slipping a clutch and thats not good.
i wish i could go 2wd,but its probly good i cant

 

I do that

And have that

and I do that

 

I didn't do all of this to drive it like a grandma. I get a smile on my face every time I fire it up.

The look on the unsuspecting mustang/camaro owner's face after you hand them their @ss in a 6000 lb suv is priceless.
