    I'm swapping over to a 465-208 and want to keep 3.73 since i don't want to do two gear swaps for the price. I currently have 35's. my onlyother rig with 35's had a th350 in it and I know the the granny of the 465 would let me keep the 35's with my 3.73. is my math working or will it be a dog? this is going in a tow rig.

    my friend has 4.10s with a sm465 but he also has 39.5's with a hot 358.

    my burb use to have 4.10s but ti also had a diesel with those 35's. or should I just put in 4.10s now knowing i'd want bigger tires later on ,LOL

    I ran 35's and 36's with that combo (465/205 though) and it wasn't a dog. Decent on the highway too, mileage around 12.5-13 mpg...

    I'd say 35's would be about your max. I'm running that setup with 44's and it's absolutely terrible. (speedo says 35 when I'm doing 60 on the highway!) :eek1:

    I had a 465/205 combo with 3:73's in my '79 and could roast the 36" tall Buckshots on dry pavement and got almost 14 mpg with a pretty mild 350. I did tow from time to time with it but I definately had to use low gear. The best would probably be 33's if you're gonna be towing regularly.
