Tom hands new, Chrysler torqueflite a-904 and a-727 transmission how to rebuild, book you can get it at Amazon he's online here I bought mine from him personally and had him autograph It.

lots of guys on here running stroker motors with 500 horsepower are using the 904 s.
sounds like your transmission guy is not a torqueflite man. how much is he going to charge you to do this?

Personally I like the 742 the best because the inner pinion bearing is the largest. but personally I have never had a 741 break on me. They put them behind 383 also.
Trans shop rebuilds mostly rebuilds the modern stuff. They were more of a speed shop 20-30 year ago. He did say He would buy any 727 cores He can get His hands on! He knows there is a market for them. I just might try and locate a few and barter a 904 rebuild!
