Here a couple of sites that may be of assistance. The first link sells any part right up to full engine packages. The second site is a forum where you can get do-it yourself info.

Good luck with you're search.

The tag right on the valve cover or intake will tell you too.

I suspect GM but I would need firing order (also on the intake) or the # of the oil filter on it too confirm.!!!

The 3 liter Mercruiser is most definitely a GM block. That block has been used for over 20 years. I have a 1986 version of it in my boat. It's a tough engine.

You can also gat parts such as spark plugs, filters and some gaskets from your local ac/delco parts store. Just give them the part numbers. Usually you will save a significant amount of coin.
