I am trying to figure out if my 67 corvette (definitely a 67 by Vin #) has the original engine in it. It has had a CAM placed in it sometime in the past so not sure if the block is original or not.
The only number I can Find on the block is F0223HC. The only HC I’ve found researching is on a 65. I’m attaching a picture. Am I looking at the right number?
On the back of the block on the he flange where the bell housing bolts to on one side is the casting number and other is the casting date. Please find them and report back
Thank you. That's what I was thinking. I guess now I'm curious if it is an older or newer engine and I know it is supped up but wondering what this block was out of/stock. Any guesses on this number?
Hate to say this, but the only small block Chevy engine suffix codes of HC I can find, are for either a '58 full size Chevrolet with 283 or a '62 Chevy II with 283 and a 3-speed.
Perhaps if you could find and post some of the other block numbers (castings or otherwise) we could be a bit more definitive.
The fact that there's no VIN derivative on the pad, indicates that it's a lower horse power, passenger car engine (full size, Chevelle, Chevy II, Camaro), and not a Corvette. All Corvette blocks from mid 59 on, got a VIN stamp, while only high horse engines in other Chevrolet models got a VIN stamp, prior to when it became law in early 68.
The "HC" suffix was used on 4 different engines by Chevrolet, the 65 327/250 with a Powerglide, the 66 327/275 PG, 67 327/275 PG, and 68 327/275 PG. All were Chevrolet passenger car engines, not Corvette. Since the Flint plant code is an "F", this narrows it down to either the 65 327/250, or 66 327/275, because the Flint engine code was changed to a "V" in 67. The casting date and number are needed to determine if it is the 65 or 66 327.

Minor note: 60 Corvettes had no vin stamp on the engine until somewhere around Dec 59, around vin # 1800.

Glenn thanks for posting that. It prompted me to check in the "Lime Book 2018"... duh! Is that what you used?

You're correct, I was thinking late 1959, mid 60 production, and in my hast I shortened it incorrectly.

Yep, I usually use the Lime Book anymore, as I've found it to be the most accurate, and more closely matches what I've seen in Chevrolet Parts Books over the years.
