My input would be, if you don't want to keep it exactly original, but a driver, would be to put later axles, hydraulic brakes, steering under it. If not a flathead in it, what is it?
GMC engine SN's start with displacement, i.e. 228xxxx, etc. if an overhead valve. Stamped number on pad behind starter on starboard side, port side on big engines.
