th400 bellhousing difference
th400 bellhousing difference I am going to buy an pontiac th400. Is it the same as the chevy bell housing tranny. Since I am going to cut it off and install a jw ultrabell I dont think it matters. As far as I can tell all the measurements and converters are the same. I just wanted a second opinion. thanks

You have to cut those two big ears off the top of the ultra bell as well. Besides that and the clearancing for the 4 upper rear main cover bolts, thats all you should have to do. I just installed mine yesterday.

I did it because Rossler told me they needed to be cut off.

I didn't fit check it on the motor as I didn't want to put in and pull it out again without using a lift. I noticed the pics that Derty put up of his ultra bell also had the ears cut off. If it fits for you then cool.
I checked it out pretty well. I beveled the top inside edge (between the top two bolt holes in the ultra bell) about 3/16" though before I ever clearanced for the bolts (hoping that was enough but it wasn't) so thats probably why I had no other clearance issues. Right now it fits great.
on another note, I put in another post about the clearance between the TC pads and the flexplate. How much clearance did you guys have?

Yeah, and if i'd checked it like you did I probably would've done the same thing but just luckily it seemed to work out for me!

Also, I just checked, and other than the four top rear cover bolts, I would of had no clearance issue at all there. It was like 3/16" away from the cover itself.

This area has a min and max clearance that needs to be set, mine is just slightly bigger than 3/16" so I just shimmed it. It is now somewhere between 1/8 and 3/16". Here is what Rossler says http://www.rosslertrans.com/Converter Spacing.htm and has some good illustrations to show what I'm talking about..
