a stock long 1/2T should have a 3.90 rear and should be capable of 65 or better, although noisy - you won't find any gearing that will make it sound like 30 when it's going 60, but the 3.38 rear gears from Patricks would help by lowering the RPMs, or the optional 3 speed overdrive if you can find one
