JimW and Tom,
I would think the 4 point mount would support the weight of the 292 better. If you eliminate the bellhousing mounts, and just use a tailshaft mount, ??? I don't know; maybe we should get one of the engineering guys to weigh in on this. I will email Tremec and ask them for an opinion.

Have you received a response from Tremec engineering?
p.s. I have a 250
