  • Champion and Dana 44

    Putting in a new Cathcart stage 4 (aluminum high compression head,dual intake and exhaust and bigger valves) into a 55 champion sedan. Do you guys think a dana with 3.31 rear is too high for the 6 and automatic
    combo?

    Matter of personal preference as to how quick you want your car to be. I'd personally go with a 3.73. Think about it - Studebaker put it behind the R1 automatic which has twice the horsepower and the same weight. If they thought an R1 needed that much gear for good street performance, anything less in your Champ will accelerate commensurately more leasurely. thnx, jv.

      I beg to differ with ya Pack, the R1 Automatics had standard 3.31's![:0]
      Both my JT R1 Auto. '63 Hawk and my '63 Avanti R1 Auto. have std. factory ratio TT 3.31's. That's what the brochure shows as std. [^]

      The ones you are remembering are the 4 speed R2's, they did have the 3.73's standard. They went "all out" to make those very fast, right outta the box! [^]

      It doesn't change Dancy's situation however, if he wants that "Hot Rod" 6 to go better than a stock one, he still needs at least 3.54 to get it going!

      In my deleted answer to his deleted post I said that I recommend one of the Internet Calculator sites to determine what his RPM's would be at say 65-70 for cruising & fuel mileage (if there is such a thing with dual Carbs.!) Here is a good site for rear end info:

      Hey Dancy, don't forget to get a replacement rear section of driveshaft for your car or have it shortened, it will need to be shorter with the larger 44 replacing the 23 axle! [^]

        Thanks for the info. Stephen Allen has the driveshaft needed and he is right down the road. I am going to get new steel wheels to clear the disc brake set-up on the front of the car. I think some Ford rims have the right off-set? I want to stay with the close to stock size width tires.

          Ford or Chrysler. I think that the "Intercepter" Crown Victorias got
          16 inch steel wheels. I remember reading that somewhere. You have
          to figure out what your current offset is, compared to factory Stude,
          and go from there. It all depends on the rotor/hub used.

            I've driven many six automatics - I'd go with 3.31 or 3.53.....Don't let anyone talk you into a 3.73 or numerically higher. With a 3.73 or 4.10 in a six car with automatic its almost impossible to drive it over 65 without the engine revs becomming high and it sounding like the little pistons want outside their cage [engine block].

            My 54 champion is 3spd with overdrive and a 4.53 rear axle. With overdrive this equates out to about a 3.4 rear axle ratio if I remember correctly. This is a very nice driving car that can stand modern highway speeds.
