The Stovebolt Site Forums The Shop Area Engine Shop lookin for input on gear combo

Just looking for some input if this is agood combo??? I have 53 chevy 3100, engine is being built as we speak( 292), I have a saginaw 4 speed(2 groove with 3:11 first gear, and a posi rear with 3:23 gears,, I have not bought rear yet,, just waiting for input if this gear ratio will work for everyday driving .. the 292 will have lump port head and 4 barrel,, all goodies done to it,, should be pushin aound 250 hp,, 300 foot pounds torque or so...

With a GMC 270 and an SM420 (3.58 second gear) with 3.08 rear gears I get along fine until I hook up something like a tandem axle car trailer.

3.58 x 3.08 = 11.0264
3.11 x 3.23 = 10.0453

Your total ratio in your starting out gear isn't quite as deep as mine, but your hot rod 292 probably pulls harder than my stock 270.

In everyday driving, with a minimal load and no trailer, I think it should be great. Add a heavier load or a trailer and you may not be satisfied.
