I have a 1950 Chevy 1/2 ton pickup. We found a chasis that already has a newer differential currently mounted. Right now, the body of the truck is totally removed from the chassis and are in the process of assembly.

I want to place a 350 with a 350 or 700 auto tranny in the truck. To do so, I plan to mount the cab and then attach the tranny to the engine and hoist it into place using the hoist coupled with a transmission jack to position the engine assembly in place so that I can figure out where to put the engine cross member support and the transmission cross member support.

What do I need to consider? Is this a good approach? I understand that the alignment of the transmission yoke with respect to the differential yoke should be within 3 degrees in both axses?

I assume I need to place the engine as close to the cab as possible?

Your insight would be very much appreciated.
