the 3:73 gear ratio is a good street/strip the 4:11 works just as good
on the street as well, what carb and intake are you using, and
you said mild sbc, roller or hydralic cam? with the right combo the
3:73 had worked great with my 383, if your sbc is stock you might
try some mods to boost up hspwr, using the 4:11 with no changes
to the block might give you a slower time, not sure, have never tested
on a mild sbc, i could be wrong, good luck bud :wink:
