im getting ready to do this exact thing. 1975 od trans in my 198 slant duster , with factory rear I have no idea the gears in those cars but figure its 2.73 wish realm ? does that sound right ? I want the over drive as I take it on long highway trips like moparty and power tour and I think it would help a lot. are you saying its gonna be a issue here or jus that is pathetic with my rear in it ?

I have my 65 Valiant Wagon set up with a 170 slant and a 1965 A833 with the 3.09 1st and 1 to 1 final drive infront of a 323 7 1/4 sure grip and it is a fun car to drive.I take it on long trips up to the Adirondack mountains and she takes the steep hills fully loaded with all my camping gear ,tools and what not with no problems at all. Gets around 24 MPG . For just a driver this set up is really nice. You won't win any races but the car will get out of it's own way.
