I have moved motor mount pads both ways, and it's a pretty simple swap. I replaced a 292 in a big step van with a 350 and moved the mount to the rear, which was not a good thing to do. The 6-cylinder had more load pulling torque than the V-8, especially since somebody had installed a cam that was more at home on the drag strip than in a 10,000 lb. GVW truck!
