Question on Gearvendors overdrive . Is it a basic bolt in operation for a

jerry6 said

1970 Dart , 340 with a 727 ? I drive a lot of highway just to get to the track 45 miles at 3200rpm is just killing me . With the O/D i figure 2000 or less highway and great at the track with 6 speeds .
Are there mods to the floor pan on the A body ? And would you buy one 2nd hand .
Thanks , first week with the car , thought it would never get out of storage with the weather we have had .

I love the idea of a Gear Vendors, in fact I've been offered a brand new unit as a trade for some video work a local business wants done, but seriously you can't drive 45miles at 3200rpm?

My closest 1/4mile is over 200 miles away and 3200rpm is nothing compared to buzzing along at 4000rpm+. I wish I had a GV in that car.

Fitting a GV won't drop your RPM below 2000rpm, it'll drop it to about 2500rpm and that will depend on what converter you have.
