Its a z code 390, as far as I know its all stock. I haven't done a compression test yet, but it runs nice. Unless the compression test shows crappy results, I don't plan on even cracking the engine open.
Really? It seems like after this much time has elapsed it would be a good idea to thoroughly go through and clean everything up even if no parts wind up being changed.
Besides, with a few modern parts it could idle as smooth as stock yet make more power and use less gas all at the same time.
