I have also seem many GM automatics that had both the Chevy and the "BOP" bellhousing patterns.

Phil,
Like Mark said I have no idea why a Pontiac guy would do this. For the amount of work it would take it would be easier to stuff the guts of the transmission into a BOP case. All the same trans used in performance applications the Turbo 400, 350, metric 200 and PG were all available with a BOP case and there are lots of cores out there. And as Rory said there is also the dual pattern cases.

Maybe the chev case is stronger than the BOP?
Anyway's I wasn't trying to pick on the guy's that did it, Just knew that it had been done and that it was protested and NHRA did nothing about it. Now back to the subject, Mark, Can I bolt a 727 tailshaft to a 904? I don't want to build a new driveshaft, LOL

Don't know that one .I'm a GM guy, and an occasional C4.
I'm sure someone here can tell you more...Maybe Alan?

Phillip: I Do not believe that it would be very possible or economical to exchange Tailshafts......................................
Trans output shaft are different in length and diameter as I recall andmaking a output shaft would be a small fortune. Both tail shaft have rear mount in same place and take same transmission cross member . The yolk is twice the size on front of drive shaft on 727 than on 904. Nevertheless , it would much easier to make a new drive shaft or rework a stock one than modify the transmission! I am sure that there are some transmission builders than can give you better advise than I can.................I have not rebuilt my transmission since the 80's. More effective to just cut a check to Pro Trans and cheaper in the long run with my skills. Phillip: Will answer your E mail tomorrow. |

I don`t know Jeff. I`ve seen the multi pattern Turbo 350`s & 400`s in a number of none Caddilacs. Not sure what the reason was, other than maybe streamlining inventory?

Like Mark, I do a lot more GM stuff than anything else, I can do all sorts of tricks with GM stuff, from PowerGlides to the latest stuff. The Ford and Chrysler stuff I can build really nice race transmissions with, but "trick interchanges" are out of my league.
