Hello, I m a proud owner of a 1971 Barracuda.It has a Indy headed 440 + .060 13.8cr,comp cams solid cam, 727 trans with a TCI 5500 stall converter and a TCI brake. 15 X 14 Centerlines with 14 X 32 slicks. Mark Williams yokes and chrome-moly drive shaft. 8-3/4 rear end with Mark Williams end caps and a 4.57 Richmond Gear. Car ran 10 teens @ 131 mph with Richmond 4.30 gears. Car has not been run with the new 4.56 set-up. I bought this car as a rolling bare shell and I completely built it outside in a storage facility. It took a little over a year and a lot of money but it was well worth it. With the exception of welding in the cage I did all the work myself. There are more pictures of the car at http://home.earthlink.net/~bearacuda .
