I am going with a smaller cam
the TB Convt stalls at about 2800- 2900 behind the 408
with the tb stall the cam works ok but would work better with a 3000 stall.
i never got to the track with this cam but i does pull hard and should be able to get you into the 12's with a nice set of heads and 3000 stall.
Comp Cam $360 shipped
236/238 601/605 113
Is like new only has a few hundred miles on it
It works great with a 3000 stall
i am putting in a smaller cam because i went to a tb tq.
I also have a Z06 oill tray that goes under the intake it is brand new i ended up with two of them so i am selling one.
$120 shipped
