Hello, I put this post here after being turned down for an answer on the k5 forum. I put it on the k-5 because there was only a handfull of posts on the s-10 forum. This isn't a brain surgery question and I would hope there is someone out there with access to a picture or two. And to reply to those who did answer: Yes, the basic block is the same as most 2.8s. As i indicated in the text (and yes, it is long), changing brackets, etc, also means water pump, timing cover, oil pan and maybe an oil pump. I didn't go this route, cause it's too much pain. I was hoping for a simple swap but the junk man gave me a riddle. I did the exhaust manifolds and that was more pain than i wanted. (two broken off studs to drill out) Ok, here goes the meat of my post. I have an 85 S10 4x4 blazer, with a 2.8 that knocked bad. Got a "new" 2.8 engine from a yard. It's good, I heard it run smoothly before they yanked it. It was supposed to be a direct bolt swap. Buy wait, the engine wasn't an 84. From new gaskets and gook squeezed out of joints, it looks like it was rebuilt. Based on cast numbers, engine rebuild guy said it could be anywhere from late 86 to 92. Apparently chevy did not date blocks. As i found out, the basic block is a direct swap, but not exhaust manifold, water pump, fan, etc. Unfortunatly, i did not get the fan, fan pulley, altenator, air pump, or ps pump. The yard is an hour away and after a hassle, I finally got most of this stuff. Didn't get some of the brackets though. Identifying them, what year they came from and belt path is my question. More information: Engine had a carburator, but no mech. fuel pump.(it had an electric, and i have that) it didn't have an ecu or any electronics. I plan to keep it as a carburated engine. It also had a serpantene belt and not a vee belt(my 85 had both vee and small serpantine). Swapping stuff from the old engine would have included swapping water pump, timing cover, oil pan and maybe oil pickup. (too much of a pain). I think I got the belt path figured out, but would really like a detailed pic of the brackets with altenator, etc mounted on them. The engine will go in this weekend and except for the brackets, it should run (at least for a few minutes until i shut it off for no belt and no water pump) I don't really care what year it is at this point, just as long as i can find the brackets. So anyone who thinks he knows what year it is and has a pic or can take one with a digital cam, would be greatly appreciated. Oh, it has no AC, by the way.
