Hey guys, I was wondering what y'all could tell me about the engine in my '74 260. It's stamped L28-368548 (P79). The site I checked out told me that it's a 280 engine (L28) from about 1981 (P79). Is that about right?

81-83 280zx's would have a P79 head on a F54 block. As long as it's not a turbo, that would be the combination.
