I have a 78 chevy G20 292 three speed colum shift that I just changed the rear in. I went from the stock 3.42 to a 2.73 in a effort to get better gas milage. It works great on the highway. But now I have another problem. Specifically first gear is to high. Can anyone tell me what the gear ratio is in this trans and what four speed trans I can put in to get a lower first gear. I'm not looking for a stump puller in the 6 or 7 range just something in the threes with a good spread between gears. I climb a fair amount of hills in this area and would like something that I don't have to shift two or three times before I get to the top.
