I've searched and found that in order to install mt th400 in my 67/conv , I will need a new crossmember. My question is ,I used my polyurthane small block engine mounts. Will the TH400 still mount to the new cross member?

Yes, it should. It's just that various years and engines sat in the engine compartment a little differently due to different height and width motor mounts. pdq67

The turbo 400 is also longer than PG, turbo 350, 4spd, 3spd, which all are the same length, by 1/2 inch or so, which makes the need for the 400 crossmember, which sets the trans mount rearward to compensate for the extra length.

UPDATE...Installed the new crossmember this weekend. Aside from drilling 2 new holes into the frame. It fit perfect, even with the smallblock motor mounts.
