Tremec TKX in 67-72 Chevy Truck First Drive on Highway 

It's got a 2.87 1st gear and 0.68 5th. The rear end is 3.73

@@pjmoreland are you happy with that ratio? The truck guys ive spoken to have mostly gone with the 3.27/.72 tkx

@@LocoF111 I like having the taller first gear. The TKX replaced a 700R4 which had a lower first gear that felt too low to me. I do have small wheels though at 26.25", so that makes a difference.

I wonder how it would be with 3.73 rear and 29-30 inch tires. This is the same trans ratio I plan on buying in a few months.
