what have you gotten done on your blazer today?
Not a thing as of yet since I'm waiting for my son to get motivated as usual. I have an 85 4x4 S10 which I bought for my son. The 2.8 (which I've learned have a notoriously weak lower end) had thrown a rod. Surprise! Surprise! Luckily I was searching forums like this one after finding out the three 2.8s I'd located before buying the Blazer had all been sold and found out the 3.1 was better and now we're getting close to putting in a 3.1 out of a 91 Camaro.
Next up I have to set the rockers, then put on the valve covers, flywheel, and motor mounts. After that I'm hoping we can get the old cracked out tires to hold air long enough to move the Blazer under the tree and drop it in.
Then I might have some puzzle work to do as I'm not familiar with these and the old man I bought it from already had everything disconnected. I haven't had any luck (though I haven't tried too hard yet) finding any pictures of engine compartments so I've got something to judge by while figuring out what hooks up where.
So, does anyone have an 85, or something that's the same under the hood, who has or would post some pictures of everything under their hood?

Just have to figure out where the temp & oil pressure sender wires are, and pick a positive connection for the alternator. That's the trickiest part if you can't find the OEM harness connection. There's plenty of alternator wiring diagrams on the net, so it's not too bad. I just used one to put an alternator in an old home-made Wisconsin-powered logsplitter I got running for someone. Works great! Going off memory I think I just jumped 2 connections in the alt. together, then ran a 3rd right to the battery - that was it. Was a V-belt alternator off a mid 80's full-size, so probably the same as what you've got in yours.
Thanks for the reply.
That one should be a piece of cake, since it's carbureted, and has no electronic controls. All you need is 12v switched to an HEI ignition, fuel to the carburetor, and it's off and running. Nice and simple, like the 4.3 I stripped down for the same setup.
