Please do not take this the wrong way but this does not make sense to me unless they used the BB motor mounts as well.

Maybe because the new Camaro had a different subframe so the Z28 TH400 crossmember wouldn't work so they used the BB TH400 crossmember. Up to that point in time, there wasn't any smallblock using the TH400, right?

This is a 4speed car, not a TH400 car. To my knowledge the TH400 crossmember is the same regardless of the engine size.

All Yenko Deuces came with a BB crossmember, and you are right it doesn't make sense. BTW, it's not a Pontiac member either, which looks exactly like the BB one but doesn't have the 1/2" offset. We do not know why they came this way, but they did, and they do not have the BB engine mounts - which makes the trans mount fun to install

One theory that we have is that the BB member was included in COPO 9737. #9737 had been a BB specific COPO since '68, and when it was modified for the Deuces in '70, the BB member was not changed to the SB one. It's a long shot, but right now it's our only shot.

Thanks Marlin, I've learned something new.
Glad I don't have to try to push my trans over 1/2" to get the bolts in mine.

[YENKO DEUCE REGISTRY]

It's a pain, the first time. I've learned that after it's installed, you can remove and re-install much easier.

[YENKO DEUCE REGISTRY]

So Jeff, what's the verdict?
