Hello all, I own a 77 280z. I recently ruined my N42 head and found a N47 head on what appears to be a 78 280zx in a junkyard. from what i see so far the head is compatible with little to no modification. I know that a few people have done this swap and i was looking for advice or warnings that people have. Also, which camshaft would be better to use? If i switch camshafts do i need to switch cam gears or are they the same? Are the zx injectors larger and swappable with the 280? ANY ADVICE IS GREATLY NEEDED. thanks in advance for any comments
