    I have a 83K5 that I changed the 6.2 clanker diesel to a 1993 model 454 with TBI. My 700R TV cable is giving me heck. I cannot get it dialed in. (I had a TBI shop put a perversion for the TV cable, but I do not have full travel. Yes I pulled the pan to verify the plunger action). So, what transmission can a man change to? My primary purpose is to yank the travel trailer for the family then escape and go offroad...Oh, and of course eat jeeps for dinner...
    I think my transfercase is a 208, I have 3/4 ton suspension and axels in the yard as my next money hole :)

    Thanks in advance for any help,

    I think the easiest swap would be a 350 turbo . Real easy swap and tough as iron and easy to get . Not sure if it will work with transfer case .

    It sounds like you have the wrong cable their are different lengths for a 350 motor and the 454 the 454 is longer also only go to a dealer to get Tv cables nothing else works.

    I did get the longer cable from the dealer so it would mount to the manifold, already, thanks.
    However, the length of the cable should not effect the travel? Right? Only where you mount to the manifold?

    I JUST GOT DONE GOING THRU THE WHOLE DEAL WITH "THE SWAP". I WAS DEAD SET ON PUTTING A 350 IN PLACE OF MY 700R4. I PICKED ALOT OF BRAINS ON THIS AND WAS TOLD BY A LOT OF TRANNY PEOPLE THAT IT WAS BEST TO LEAVE THE 700R4 IN PLACE. THE SWAP IS FAIRLY EASY, YOU NEED AN ADAPTER (ADVANCE ADAPTERS), AND YOU NEED TO CUT AN INCH OR SO CUT OFF OF THE TRANNY SHAFT. AFTER TALKING TO PEOPLE I REALIZED IT WAS CHEAPER TO REBUILD THE 700. THE ADAPTER RAN ABOUT 250, THE REBUILD ON THE TRANNY WAS ABOUT 300-400, I DONT HAVE A 350, ABOUT 150 IN THE PAPER,AND THEN ALL THE ACCESSORIES, COOLERS, DIPSTICKS, CONVERTOR, DETENT CABLES......I PAID 550 BUCKS TO HAVE MY TRANNY REBUILT. GOOD LUCK WITH YOUR DECISION.
