I'm considering changing my 3.73's to 4.11's should I see much of a 60ft difference? my set up is a mild sbc,4spd,12 bolt 373,26x10x15 m/t slicks.My previous 1/4 mile times have been very disapointing and every one says its my gear ratio? my 60 ft has been between 2.05 and 2.09

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:

10.5-1 comp. 292 duration 510 lift cam, edelbrock performer rpm heads, victor jr intake, holley 750 dp. hope this helps

yea with that combo you would benefit with the gear change, the
vic jr is a very good flowing intake, you might consider a 850 dp
running that compression, you will always have to use high octane,
your cam is over .500 lift, is it roller or hydralic? good luck bud :wink:

I had that same combo in my chevelle almost except it was a 400 instead of a 383. I had a 4.10 gear 60' were 1.71

SO you guys think its worth the time and $$$ to change to a 4:11 gear? Do you think I will see a noticable difference?

I think the ? is how are you leaving.

rev it to 5000 and side step the clucth.

or do we come out easy then stomp it.
