Seen flex bands rip the welds before in both small and large box trans. Not dependent on which engine it’s behind.
It’s all a matter of quality control at the band manufacturer.

Improper design developed for a certain purpose usually results in a design change later because of frequent failures.
We used flex bands for years and years with no issues in production. A bad design wouldn’t have lasted that long.



they were factory bands. First time was shortly after I replaced the original 318 with a mild 360. Pulled the trans, found the issue, put another factory band out of a spare trans in. Same thing happened. So I pulled the forged band from a 68 trans and no more issues. Maybe I am just unlucky, but that 360 wasn't all that warm. Just a Performer intake, 600 cfm Performer carb and a 340 4bbl cam, it was originally a 2bbl.
