Reg Evans Posted January 28, 2009 Report Share Posted January 28, 2009 How about installing a complete rear end from a 3/4 ton truck of similar vintage with 4.1 ratio. Then ad some tall 750 tires to help lower the rpm's. Quote Link to comment Share on other sites More sharing options...
PatS.... Posted January 28, 2009 Report Share Posted January 28, 2009 I have an old motorhome that has a good rear end that will be going under the 62 Dodge D300 I bought last summer. Looks to be a direct bolt in swap. Gets rid of the obsolete six bolt split rims and updates the brakes along with decent highway ratio. The whole motorhome with a good running 440 was $200.

That '62 D300 sure shares a lot of sheet metal with the '63 D200 I once had. Just an extra fill piece at the bottom front. A "D300" badge instead of a "D200". Same small rear cab window. A solid dependable truck. Quote Link to comment Share on other sites More sharing options...

MBF Posted April 17, 2009 Report Share Posted April 17, 2009 I just installed a used 4.3 in mine that I got out of a junkyard. I was amazed how easily it came out of the parts truck (had been sitting for many years). I can run along at a little better that 45 comfortably according to my speedo, but I think its reading a bit slow. I'm planning on changing the 6:50 x 16 duals in the rear to 7's or 7.50s to give me a little more speed and keep the original look. I chose to replace the carrier assembly instead of a rear swap to avoid the engineering problems of moving the spring perches, etc. I wouldn't go much under a 3.9 if I were you-I think you'll be short on power.
