Yes. The 352, 360, 390, 406, 410, 427, and 428 are all FE's and are based on the same engine block. I have a 76 F250 4x4 highboy with a 390 and my brother has one with a 428. The engine mounts are the same and the 428(also 427) will bolt directly to your transmission (NP435 or C6). If you have or are building a 428, remember this engine is externally balanced (the 390 is internally balanced) so the flywheel (if manual trans flexplate if auto) needs to be balanced with the rotating assembly.
