Brice what rear end do you have in your Bird? 63 mph at only 15 hundred rpm.

Rear End, Speed verses RPM

Post by mr71transam on Wed Apr 18, 2012 9:26 pm

Bruce I like it. Did the gearshift plate come with your shifter or did you have to make it.

Here's mine

I'm with Rich about 2700rpm at 65 mph. I have a 308 rear end.

I cant drive in town in high gear it likes to buck.( I usually up shift it at 40 mph) The tranny is from a TTA, so it locks in 3rd and 4th.
The plate to modify the shifter I did put in my OEM shifter, but it was not needed on the D/G Hurst, nor would it fit
The shifter ball I found at Performance years and liked it. Im not a "handle" kind of guy.
