Ok gang, here's the deal. I visited an old friend over the weekend. We were good friends as teenagers, but like a lot of people, we lost touch as we got older and we just kinda went our seperate ways for about 20 years. I recently learned that he lives about 2 miles from where I live so Sunday I decided to give him a call. He invited me over to his house and we had a great time talking about the "good ole days".

Well, as it turns out, he is into old chevy trucks also and he is in the process of working on a '54 3100 that he bought about a year ago. The 235 that was in the truck wasn't salvageable and he has decided to replace it with a 350 that he has already reworked and another 3 speed trans for the 350 (not sure exactly what it is).

My question is this, will he need to also change out the old rearend?

I don't have a clue when it comes to this sort of thing and he never mentioned it, but I seem to recall reading a post somewhere concerning this subject, something about the gears or whatever will not hold up to the rpm's of the larger engine. Any help on this subject is greatly appreciated. I don't want to see an old friend put all that work into fixing this truck only to find out later that he should have changed the rearend before hand. Thanks

Old trucks never die, they just find a new home.
