Overdrive on 318 Poly

[Rangepony]

Wondering if I should upgrade my transmission on my 64 Fury Convertible with 318 Poly. I have the stock auto with push button...it works but seems a little "clunky" to me....was wondering if I should go something more efficient like an overdrive....my plan is to use this car as a highway cruiser to go to the coast or mountains...

Overdrive suggestions and amount of work involved.....?

Lots of work.

It will need either a later model 727 installed with a Gear Vendors overdrive or you can do a 518 with factory overdrive. The Gear Vendors will be a little smaller in the transmission tunnel whereas the 518 will require some surgery. It's pretty spendy either way.

Service/adjust the existing transmission. If it's working properly it will be far from clunky. It's probably already got a 2.76 rear, perfect for highway cruising.

How fast are you running. I recall my 59 Fury would do 80 easy enough. But the bias tyres were not up to the job of making the car go where you wanted to.
