I once dropped a 327 and TH350 in a '53 Ford F100. Also installed a 12 bolt posi in the same truck. Used a Hurst prefabricated front motor mount and had to fab rear mounts and tranny crossmember. Used a piece of rectangular tubing cut on an angle to bolt the Hurst mount to. Boxed a 24 inch section of frame where the front motor mount went and welded in the cut tubing. Installed the rear end with coil springs and a four link kit from Summit Racing. Had to fab the spring perches. Summit carries alot of easily adaptable mounts. I did that 23 years ago when I was 16.
