Hmm.. An interesting turn of events. The VIN came back as a V6. This is not a V6. It quite clearly says V8 on it. It makes me wonder what the V8 is from, or what it came out of at least. Any way I can check? This means someone already did a tranmission\motor swap..

There should be a casting code on the block. This web site may be helpful for you.

Awesome! Found the code after some digging about. Got under the car with a flashlight, and wrote it down. This is the closest match I have: 10125327 1992-96 350 300 & up 2/4 Gen.II LT-1, reverse flow cooling

Dude it sounds like you already have an LT1! Are your heads aluminum or iron? You should be able to tell just by looking at them because aluminum doesn't rust and should still be silver. Just to make sure it's an LT1, is the distributor mounted on the front of the block?
What does the intake look like? Its not an end all answer to the question but it may help us figure out what it is. Can you get some pics of the engine?
Also, where do you live in Missouri? I live just outside of Kansas City and might be able to help you where I could with id'ing it. Plus there is a great board (www.mofbody.com) that would be more than willing to help you. There are members on there from all over Missouri.

I live in Lees Summit, actually. Not too far from Kansas City. I'm looking around on google for the closest thing to my engine, since I don't have a digital.. Gimme a bit and I'll have a pic up.
Closest I could find, looks almost exactly like mine (I don't have a CAI)

I bought it on Prospect, down town. 117k miles on. I live right near Lees Summit Highschool. You don't happen to own a black Camaro, and streetrace with a couple guys in T/A's on weekends, do you?

That sir, would be an LT1 from either an f-body or a vette! Looks like you lucked out! LT1s from f-bodys and vettes came with aluminum heads, while the rest came with iron. If it is a vette block it will be a 4-bolt main block as well, but if it is an f-body block it will have 2-bolt mains like the rest of the LT1s (don't ask me why they did this). The block castings are still the same though so you cannot know which one it is unless you pull the oil pan. Regardless, you have no less than 275 hp at the flywheel, which will translate to 230-250 at the wheels depending on the tranny it is running through.

Man! I do feel lucky.. I'm also glad the guy didn't know what he had! He had it listed as a 5.0 V8.. And I believed him. I got questiony when I ran the VIN, and low and behold, it is an LT1. That's so awesome. 
How and where do I check the bolt pattern?
How and where do I check the bolt pattern? Looks like you lucked out! However, it doesn't look like they did the greatest job of swapping it. I would get that alternator swapped out asap because it doesn't look like its held on very well. If I was you, I would start by swapping out the exhaust. I bet it isn't the greatest as it is. Got any pics of the car?
Nah my car isn't black. What color are the trans ams? I haven't seen them around? My car is actually white and not running right now. When its done though I will be rolling with some friends over in Kansas for some racing.

Yeah, we head over to Kansas. One kids T/A is green, his dad owns Midwest Transmissions in Raytown, and the other is black. Then there's the black Camaro. They all run good, and sound amazing. My 06 4.6 Mustang runs even with them usually 
I've not thrown the Camaro at 'em yet. Don't imagine it'll fair well against a bunch of mildly-modified T/A's, but I'll have fun trying. I'll get pics when I can..

The bolt pattern on all LT1 blocks is the same as any gen 1 block. The difference I am talking about is on the main caps which are located inside the engine right below the crank shaft. A 4-bolt main engine will have four bolts on each main cap, while a 2-bolt will only have two on each main cap. In order to see the main caps, you need to remove the oil pan. Either way you have a good engine, the 4-bolt engines are just a bit stronger but a 2-bolt can take a lot of abuse as well. Note that a 2-bolt can also by splayed to a 4-bolt, which some actually argue is stronger than a factory 4-bolt block (dunno if that's true), but most don't go to the trouble of turning their 2-bolt into a 4-bolt though unless they are building a pretty serious engine. The only real reason to know which you have right this second is if you want to know for your own knowledge, so personally I wouldn't go through the pain in the *** of pulling the oil pan, but if you want to go right ahead .EDIT: I just read the rest of your post above. Stock for stock, LT1s actually run a similar 1/4 mile to the S197 mustang GTs and 3rd gens are lighter than 4th gens, so even if you don't beat the mildly modded cars (assuming you mean bolt on kinda stuff), you shouldn't be too far behind

I'd first try and get the complete lowdown on what is in the car. Call the previous owner and ask him for everything he knows about that's in it, or done to it..
