The motor mounts will support the SBC alone. I'm not too familiar w/automatics. My '71 GMC Jimmy has the SM465 4-speed manual [+NP205 xfer case]. I know I've seen transmission mounts for automatics, but not sure how they go in. 4x4 transmission/transfercase set up is a bear. I would not do that alone. For safety reasons, even if it were a 2wd, I would try to find a buddy to help with the Xmsn part, but a self-reliant spirit is good.
