I got a 57 210 that has a 85 Chevy 350 in it with a mild cam and a 600 cfm carb. It's a daily driver that gets about 90 highway miles on it per day. Right now I get about 14-15 mpg with the original 3 speed in it, and have concluded that with gas prices as high as they are, the cost of a new clutch and a used tranny with overdrive could be paid for very quickly. I was thinking about going with a Borg Werner t-5 from a 83-92 Camaro, but am not set on that if their is something better to use. Any shared thoughts or expereinces with this would be greatly appriciated.

Welcome to DACC forum. The stock overdrive would be the easiest install, if you could find one. I think it gives a .7 overdrive. You wouldn't have the linkage problems or have to go to a floor shift, which is sometimes a problem with the bench seat in the way of the floor shift. What rear end ratio do you have? A different rear end ratio might help also.

I still have the stock rear end in it. I may be wrong, but isn't it a 3.55?

I sent you a long PM and wondered if you got it. I am no jgood with computers, so I wanted to make sure I did it correctly. Larry
