    Man, I'm sorry to see your engine that way. If I had the stuff you needed, I'd let you have it. Let us know what you need and maybe we can help out.

    That's what I'd do. Vortec 350 and be done with it.

    Pulled the rest of the rod bearings, every single one was spun and burnt out. Main bearings are pitted and have deep scratches all throughout. This block isn't going anywhere without major machine work. The crank journals are horrendously scratch and ridged. None mic the same.

    You're done. She's toast.

    The GMPP "Universal Replacement 350" long block is your friend in situations like this. You can't rebuild that motor for less than a new one would cost unless you cut a lot of corners.

    http://www.jegs.com/i/Chevrolet-Performance/809/10067353/10002/-1

    Comes with a warranty. And it saves a lot of time and heartache, too.

    If you still don't like that pricetag, there are always aftermarket rebuilds, but my experience with them has been a bit spotty.

    Now, if you have a little MORE money to spend, you can get a complete Vortec truck motor for a little over $2K (from the GM mothership, brand new). You will still need a Vortec intake manifold (additional expense) but it will otherwise bolt right into the car.

    vortec motor has no fuel pump hole in the block. and you need a new intake and fuel system. keep looking.its not gonna be a cheap swap.

    my understanding is i can get all the parts needed. so i can get the electric fuel pump from the yukon, and almost any other part i need.

    Fuel pump from the Yokon should be in the fuel tank. As said above, it's not a simple drop & swap to put an EFI engine in a 2nd gen.

    If I understand you situation correctly, this is not an everyday driver. An immediate cheapest route with some sort of reliability and warranty would be a rebuilt long block. But like Damon said, they're sometimes a bit iffy. And since you haven't driven it in a couple years, just put it back up and start saving for a good replacement engine. MarvD doesn't show up here very often now, but one of his sayings is that only a rich man can afford cheap parts. IMHO
