Overdrive? I've got a 340, 4 speed, with 3.91s.
I giggle like a 6 year old girl every time I drive it!

You bet I would giggle to.
I have a 340, 904 auto 4:10 gears And with the Gear Vendors over drive I can do 70 mph all day at 3 grand on the tach. Sure like the idea of a 4 speed good combo you have there sir.
