Do these GM Performance LSX blocks accept TH400 BOP pattern trans?

As title says...anybody know if they accept the BOP pattern? Thanx.

Not that I've seen....

If I remember correctly, they use 5 out of 6 bolts on the standard chevy pattern. I may be mistaken since it's been a long time ago since I did it.

We use the universal JW bell bop/chevy pattern on a th400, as Cal stated 5 of the 6 bolts are used.

As mentioned before, the BOP bell is a little different than the standard Chevy bell. The Chevy bolts right up, but one of the holes is not used.

I've got a new LSX standard deck block on a stand in my shop. Chevy bellhouse pattern only. Ultrabell or stock Chevy case will be the best bet.
