Can anybody decode my deck pad stamp next to my water pump? The code is CC6-197. I haven't been able to get a look at the stamp code on the back yet, but I have been able to find the "star clock". So I'm not exactly sure what generation block I have. I have center bolt valve covers, and the dipstick is on the passenger side.

Nothing? No one? :confused:

Can you post a picture? I don't know what it is but I would guess it to be an over the counter bare block (Counter Case) but this is a guess as I really don't know. Is it a small block, big block, 2 bolt or 4 bolt main?

I have a GM goodwrench 454 that was a over the counter engine and it had some type of CC***** number on the pad. It was manufactureed in the 1980's.

If it has the dipstick on the left side, it should be a SB

Center-bolt valve covers say it's a small-block, and if the dipstick is on the passenger side, that pegs it as 1978 or later. It's a service replacement of some sort.

:beers:

It was sold to us represented as a 383 stroker. It makes good power but I'm not sure it's a stroker. It's definitely a smallblock, but I'm not sure if it's a 350 or a 305 or even a 383 that's just not very strong. There is a vacuum canister hooked up, but the cam has no real lope and it idles extremely smooth. So I'm almost 100% sure it's not stroked. Who strokes a motor then leaves a stock cam and heads on it? Also I just met a guy with a firebird with a Pontiac 350 that seems to be a physically larger engine. It could be just because he no accessories and a mostly empty engine bay.

Pontiac 350 isn't a relative of the Chevy 350 except being built by GM.
Absolutely nothing interchanges and the Pontiac used the same external dimensions since 1955 (287 thru 455)
