904: should I switch to 727?

forphorty said
I would suggest a shift kit or valve body upgrade for ALL transmissions. I put manual valve bodies in all my trans, 904 and 727. The TA RMVB in my 904 would swap right into a 727 if I were to choose to. If the 904 in my Duster fails, I will rebuild it or the other 904 in my garage. How would I be "money ahead" by purchasing a SB 727 along with the proper slip yoke rather than just slightly beefing up the 904 I have ?

I wouldn't slam the th200. I built one with stock parts and a shift kit back in about 90 and ran it behind a 400 sbc in a 78 Futura....no problems..

Built they are OK with the shift kit. Off the factory floor they were a bit limp wristed. Worked at a Chev dealer and did warranty repairs on many of those. Of course under warranty you only tear it down as far as necessary to repair the failure. The ther of course is under warranty there was no shift kits installed.
