Changeover from 904 to 727 ?

[1bolt@atime]

I have a 360 with the slap-shift console.
I am considering swapping out my 904 that is in need of a rebuild with a rebuilt 727.
Besides changing the torque converter, flywheel, kick-down linkage and driveshaft length is there anything else I should be aware of?
Is there a part number sequence I need to stay within?
Thanks

The converter and flywheel are one piece. You need an externally balanced converter for the 360. If you are staying stock get a converter for a 340 and have it balanced for a 360. The 340 has a slightly higher stall. The front yoke is different on the 727. There may be a few other things that are different. I haven't done a change in years.

O.K. Thanks for the info.

Are all 727's pretty much the same as far as linkage location and crossmember mounting points?

All 727's are not the same. If you are putting it behind a small block, you need the small bell housing 727. Look for a 1973 and up ,non-lockup convertor model.

the linkage & crossmember mounts are generally in the same place unless the trans is out of a 4x4 ,
2 ways to handle the converter , you can get a balanced converter , use a unbalnaced converter with a balanced flex plate

If it's a column shift automatic you will need the 727 trans bracket for the crossshaft it is different than a 904
