I don't know for sure, never had a blown BBC with a radical cam, but I'm bettin' that the best plan would be to leave the 'Glide in there and maybe even consider more rear gear. The only reason you might want an OD trans would be for fuel mileage and you darned sure won't get any fuel mileage with that combination, regardless of gears. If you want fuel mileage, swap in a stock 305. COMBINATION, COMBINATION, COMBINATION. Seriously, before you screw the pooch, talk with some other fellows who have this combination on the street and get their recommendations. Sounds to me like you're trying to turn a race horse into a plow horse.
