A lot of speed shops do change outs and the owner wants a bigger motor or different block. I bought mine at a Mustang rebuilder. There are several places in DFW that just salvage F-bodys and Mustangs, so engines are easier to find.
The prices on ebay are through the roof, so look for complete cars that are wrecked. You can pick up a wrecked Firebird for $2000.
One more question: Any tips on buying a LS1? I have been looking on eBay, and have noticed that there are a quite a few to choose from. I dont think I will be able to get a very good deal locally here in San Diego.
Looks like most of them run between 40 - 80,000 miles or so. When you buy used, is it best to just go ahead and have it rebuilt before even putting it in the car? Any recommendations on a source for quality LS1s?
Be oh so careful on E-bay when it comes to used engines. My first LS-1 was toast, all the way down to the lifters and cam bearings. So was the trans. I agree with Bud, best to do it locally if you can. At least that way if the guy screws you then you can choke him in person if you want. I think most of the other guys bought them from E-bay, dunno. It's best to buy a '99 on up. 98's have problems with rod bolts in #5 cylinder and they are harder to machine if you need to. I think in '01(?) the oil pan went multi-piece, dunno if it is different enough to cause a problem.
Never heard that one. I thought 97-2000 all used the same rod bolts, then were updated to non yield to torque ones in 2001. I would spend the extra money and buy ARP or Katech rod bolts anyways. They tend to be the weak link in the bottom end.
Budman, where can you find totalled trans ams for 2k? I would love to pick one of those up and resell my stuff on ebay. I would make a killing!
2001+ is ideal. They all came with the LS6 intake manifold. Also buy a new timing chain. The replacement chain from GM is the same one that is used on the LS2 and is more than sufficient. I talked to David Farmer, one of the World Challenge racers, last year and he said the stock bottom end with upgraded rod bolts and timing chain was good to 6900 RPM.

Go to your local Auctions. I just saw a wrecked LT1 car on Ebay at $250. Just got to look.

The 2001+ are under-rated in the HP area. I think they are quoted at 325, but I bet most are in the 350 range.

I probably worded it wrong. It wasn't so much of a problem as just something to look out for especially in hard use and ARP bolts do fix it. My builder explained it to me though I don't remember the particulars. In '98 engines, one particular rod bolt would break, the rod would then always swing over and take out #5. He has one in his office for display and it ain't pretty. I'm also pretty sure that they changed bolts in '99, though maybe not away from torque to yield.
Ok, I found a 98 LS1 with T56 for $3000 with 45,000 miles. Guaranteed in excellent condition. What do you think? I have looked around locally a bit, and everyone i have talked to just says "Good luck in San Diego!"

What comes with it? The '98 motor can be run with a later computer, which will make tuning easier. If $3k buys you everything (motor, tranny, accessories, computer, harness, etc) it's a decent price. If it just gets you the motor and tranny, you can do better.
It looks pretty good to me. There's nothing wrong with '98s, it's just like buying a '68 Corvette, there's a few one-year-only things that can make it more difficult.
Looks like the auction is over. Not to worry, there will be more.
The exhaust manifolds are slightly different, too. Just keep looking and hold out for one that is in really good shape. If you go with ebay, make sure you ask a lot of questions. There are some pretty good deals and there are some pretty bad ones as well. I got my 99 engine from ebay for 3600 shipped from SC to WA. This was almost 4 years ago.
And one more thing. Do not do an LS1 swap without swaping out the cam. You will regret it later if you don't.
