My '77, L82, 4-speed has a 3.70 rear end. Chevy did this to give the car some added response. However, this means that the car is a real gas hog. At 60 MPH the tach is at about 3500 RPMs. Am thinking about getting the rear end changed to a 3.53 to get the revs down and thus save on fuel. It's a big job and won't be cheap, but the car should handle OK. The only downside is that I will be changing the car, which is totally original with only 30000 true miles. Any thoughts on this?

dan did you get the ratio changed. I am considering a change also and was wondering how it came out. My 69 has 3.7 with a tremic 5 in it and I agree 1st gear is way to low, I start in 2nd most of the time but it is a bit tall. 70 in 5th is about 2360. The engine pulls good at the low rpm, and we use it for long trips.
