Ultra bell

jasper · Jul 30, 2017

Need a couple opinions. I cut off the bell housing off a 400 turbo and installed an ultrabell and bought a 12" converter. Then because I'm stupid I decide to read the instructions. They claim a 12" converter won't fit. So I called J.W. And they claimed some 12" converters may fit. Has anyone ran into this problem? And were you able to fit a 12" converter in there?

Can't you install your 12" converter and see if it fits ? :dunno:

Mine wouldn't fit.

Been there and done that, had a K5 blazer with a th 350 transmission, busted the bell housing on a new trans, so I cut it off and got a new ultra bell, and the stock converter would not fit.

some converters will hit bell mounting bolts but you can counter bore them deeper.
i had 12" once and it was hitting bolts but i just sinked them deeper and it fitted fine

Sounds like a plan. It's getting rebuilt right now. When I get it back I'll see if it works as is. If not I'll see about counter boring them. What kind of bolt did you use?

My problem was just the converter was to big around, and rubbed the inside of the bell all the way around and not letting the converter go all the way in.

used the same bolts just shortened them same amount as depth of counter bore cut was.
