Have you considered putting a TH350 in? It's a real easy swap - you don't even need to change the driveshaft.

thanks guys...if/when i do any swapping, it'll be for the 700R4...i had first thought of doing an exchange or even selling the Powerglide...however, i have the original 283 for the truck, so i'd like to hang on to the Powerglide too(that way i have the original equipment)...& if i have a good working Powerglide, i hate to just let it sit around in favor of another tranny...at least i can use the Powerglide for now & put the extra money towards other repairs/modifications...then later i can go the 700R4 route...i'll try to find a rear with 3.73's....i think those would work best since i plan to go with the 700R...at least i wouldn't have to switch gears again, which i assume i'd have to do if i go with 3.08's...would it be very hard to find 3.73's in a '71/72 rear?
