im goin supercharged on a built 4.3 w/ multiport upgrade.
I have a 2000 4.3 w/ 4l60e
With me holding the shifts till rev limit and on a damn good launch i only ran a 15.9 :bloated: the 2000 csefi makes 180 hp and 240 ft/lbs I have a few bolt ons, so for additave sakes, lets say 185, 245.
its still more than the 1994-1996 MPI motor puts out on its best day. At most, the SS is runnin 15.6, 15.7 with the 5 speed and limited slip rear
