Hello Folks, Can someone run these numbers and see what I have? I am getting two conflicting stories. Casting number on the back of the engine is 814660, which says it it out of a 1968-1969 Corvette or Camaro, but the engine ID # is 18D185727 T06I4HN, which I was told was out of a 1965 Corvette. Thank you in advance

I can't find your casting number (814660)in my book. Every block casting number I found from 65-69 started with a 3 and had 7 digits. The closest I could come to your number was 3914660. It's listed as being in passenger,Chevelle,Chevy II,Camaro &
Corvette, and is a 2 bolt 327 of various hp ratings. The "HN" engine code works with a 68 Impala, 275 HP 327. If that's what it is, it should be a big journal 327 block.

Thanks for the reply, I just realized that I gave you the wrong number. On the back of the motor it has 3814660. I don't know how I typed it wrong on the previous post. I guess I had one too many beers last night. But I did get the other number right.

engine number code 32 Bob

Bob are you sure that the 8 isn't a 9 making it read 3970010? If so then that just means that it is a 4" bore Chevy block. It could be anything from a large journal 302, 327 to a 350. This is perhaps the most common 4" bore block.
