wideglide, what i have is 335/35/17, 3.73 gear, tko600 w/.82, all neatly packaged in my jbl cobra. all gears are near perfect imo, from 1st to 5th. all useable. i don't drag race, and don't use 1st much except to drive slowly etc. but shifting through the gears i think they are spaced very well. i have a tko3550 w/.62 od in another with similiar setup and lower numbered rear gear, not sure exactly, and the 1st gear is comparable to tits on a boar and and the .62 od is nice for hiway cruising, but with the .82 od in the tko600 i can cruise and pass if needed without downshifting. i'd go with the 3.73, same size rear tires and tko600 anyday. btw, the cruise at 60 is about 2400 rpm 70 is 2800. you would think this is loud but it is not bad if you have a vacuum advance or run a lot of timing, the ignition is early enough in the cycle the exhaust noise is not bad. 1st gear is going to be useless in anything you use imo. install a lightweight clutch and they'll have to peel the smile off your face. guaranteed.
