Have one in this car http://youtu.be/Pc-4z5WrNwc 74 cuda 408 stroker and love it. Easy to install, slight dimpling in floor and minor wiring. Evidence above of abuse. Even shifted into 2nd over at the strip WOT,, no gain on my combo but good testament to the shift quality and durability. Wanted to go 518 but they were pretty hard to find at the time for any kind of fair $ and the GV 727 combo is proven tough.

I hear a lot of concerns on driveline angles but I had no problem getting mine good and its one of the smoothest 11 sec cars I imagine you'll see. Well as far as old muscle goes anyhow
