Thread: 727 trans to 318

Tweet

Can any of my mopar brethren tell me if there are different cases FOR A 727 TRANNY IN A BIG BLOCK VS SMALL BLOCK application?

I have a 318 that Im dropping in an old pickup and I have a 727 tranny that I pulled from my 383 drivetrain and want to use it behind this 318 - but I keep seeing people advertising 727's specifiacally for big blocl OR small block applications.

well, Ive answered my own question with this helpful link

http://www.allpar.com/mopar/torqueflite.html

Basically - there is a case difference - 727-a is the small block version case and the 727-b is the big block

Anyone got a small block version they would be willing to trade for a big block version? I have done some vlve body work to this unit and played around with it in my 66 plymouth/big block before taking that car off the road for awhile.

Lemme know,

thanks!

mopar makes a 727 and a 904 trans. the 904 is the small one came behind the 6 cyl. and small V8. the 727 came behind the bigger motors and with a shift kit should do just fine. one of the better trans. on the road,
