Disappointing ET's with 408

i agree with the other guys a 600 is too small. hell i run a proform 750dp on my 360.

with 4:11 gears that 60' needs to be alot better. how tall of tire? that thing needs to be atleast in the 1.6 60' area.

before you go nuts on headders and exhaust i would open it up and see how it runs. tti headders should have no problem getting you into the 11's.


sure that needs that much timing? been talking with a few local guys and they have been telling me the 408/416 motors don't like alot of timing.

i think you need to work on the tune up.
