4.11 gears?
i found a set of 4.11's for my 9 bolt and is there reason why i shouldn't get them?? i plan on mainly doing suspension mods to my car (sub frame connectors, strut tower brace, urethane bushings, lowering spring, agx shocks, ect) the only engine mods will be exhaust a mild cam, performance ignition and a more free flowing air filter setup.
is 4.11 to low? i mainly want them for freeway pulls but also occasional weekends at the strip/autoX

You might be running out of RPMs at the top end of the 1/4 mile. I have 4.11's in the '57, 27" tall DOT slicks, 4000 RPM stall, it goes through the traps at 6000 RPMS @ 106 MPH.
