i had a th350 3-speed auto in front of 3.73's in my old vette. at 75 mph i was at 3400rpm. hurts the gas $$ cause hardcore. thus, i would reccommend the 3.42's, though i dont know if it would make a worthwhile difference. bottom line is the final drive in the th350 is too short for big ratio rears to be a good DD setup.
