Yes, that is the document I used, (thanks Bill) deep in the document under "Engine and Clutch" Page 1, you will see C,K, etc. Look close at the columns, they don't say K10 all the time , just K-C10, that means K10 and C10. Three engines as I said 230, 292, 283 V8. There were only two 6 cyl in 1963 and a 4 banger. But some real cool V8's. (409, ooourah)
Rick, good points about your Docs, don't have them. You can say that your engine is stock because this post is proving it can't be disproved even though it's not listed as available.
Chevy Inline 6 Engines Casting Number and Code Guide, author: Mark S. Allen, available on Amazon.com. How does the parts catalog confirm that a 1963 K10 had a 261? Can you scan the page and post it in photobucket or other for posterity?
