Improved gas mileage
I will be making several long distance trips this summer and next, and need the best possible gas mileage. With a stock chevy low mileage 350 motor and
TH 350 transmission, what would be the best rearend to install for best performance and mpg?
If I were to change out the transmission, what would be the best transmission/rearend combination to get the best performance and mpg?
