    I ran 4" blocks on my '48 Fleetline way back in the day. No problems at all.

    With a torque tube there is no concern with pinion angle since there is no rear U-joint. As you lower the car you actually decrease the angle at the front U-joint.

    Only problem there could be is lowering to the point that gear oil flows from the rear end up the torque tube. There are baffles available to counter this.

    Would the same apply to a 54 Bel Air?

    thanks for the info guys
  7. I had a '54, back in the day, that I tried to run with 6" blocks and it would eat up the u joints in no time at all! The reason that I remember this so clearly is that I tried using them several times and they were a bitch to replace :cool:

    agreed we air bagged a buick with a torque tube and she rides quite nicely with no problems and its been done for about a year and a half.
  9. I also ran 4" blocks on my 52....basically the same problemo
