I bought this valve body off of another mopar guy. He said it was Reverse manual full race valve body for my 727. There are numbers on it but couldn't find much.
I can highly recommend TCI's Street Fighter (SKU: 122400) valve body as I've been running an earlier variation for two years. Shifts are fast and smooth and it's basically "plug and play" for installation. Price is in the $240 range and can be had at various places like Summit and Jeg's. Actually I can recommend all their valve bodies as friend of mine have variations of their valve bodies and run them without issues.
