going from 3.42's to 3.73's
 

Is there any notable gain going from stock 3.42 to 3.73's in an m6 bolt-on camaro Z.

double post
and not worth it

Move up to 4.10's. You won't regret it.

A while back a friend installed 3.73s on a bolt on car and picked up a lot. Don't recall exactly but I thought he picked up almost 2 mph.

Later, after h/c, he went to 4.10s from 3.73s and picked up almost nothing.
