    We have a 1983 Chevy C-30 regular cab 1-ton. It has a 454 with a three speed standard transmission. The previous owner told me it has 456 gears. I've never been in the third member so im not sure. Anyway I want to know if I can change to a 5 or 6 speed manual trans with 410 gears? How much of an investment is this going to be $$$ wise? And how much would this increase my mpg to make it beneficial?
