The block could be anything 69-79 including vette,the heads were on 71-82 vettes and most anything else. You might do a search on this site,I remember somewhere a thread that dealt with the "pad" numbers. I think the number you posted with letters in it should relate in some way to the vin number if the engine came in the car. The other number will show up in Hollander's manual and will tell you the application. There's a book out called "Catalog of Chevy V-8 engine casting numbers" everyone should have one in their library.

The info I've found makes it VERY unlikely that it is an original Vette engine.
I'm new at this and was having no luck decoding the pad code on the 350 in my 76 Stingray. The problem was that I was looking only at Vette sites and they only listed valid codes for vette engines.
Mine ends in CNN, which turns out to be a 1970 block that was 250 HP with a 2 barrel carb. Who knows what it is today, as it has a 4 barrel and a few other mods.
Anyhow, I found the info I needed via a printed block listing at a race shop.
I also found the same info online, once I knew what to search for (try "chevy 350 block code").
This site also should help you make sense of your numbers:

Based on the camaro site, your block was originally in a truck. (The 3rd from last character is either C=car or T=truck... your is T)
Keep in mind that I have no idea personally. I'm just passing on what I've found via a couple of sources that appear credible to my rookie eyes.
