I STILL HAVE THE 4/11 GEARS AND WOULD LIKE TO GET SOMETHING SMALLER. I HEARD THAT LIKE THE 54 CHEVYS WITH THE AUTOMATIC TRANNY HAVE LOWER GEARS. IS THIS TRUE? IF SO WOULD THIS BE A GOOD SWAP. CAUSE I WOULD STILL HAVE THE TORQUE TUBE. ANY SUGGESTIONS PLEASE HELP ME OUT. THANKS | | |

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

Be yourself. If you are ever lost, It will be much easier to find yourself if you know who you are!

The '54 Sedan Delivery had a stock 3.7:1 rearend and this vehicle with a Powerglide transmission had a 3.55:1 rearend. If the Powerglide transmission is longer than the manual transmission, then the length of the torque-tube is shorter (as in the case with the HydraMatic transmission in the 3100 truck). My guess is that the Sedan Delivery drive train matches the automobile's drivetrain but I do not know how well these matched up in length to the trucks torque-tube.
Maybe someone else will have better infortmation.
