The "RIV" in the serial number confirms it is a Riviera. 72 was right at the time when HIN numbers were started so this one may have just missed the system. However, do check the upper starboard side of the transom for a molded in HIN.

Welcome to CCFan

We all would love to see some pics.  You can also link an outside Imgur or Dropbox or Google Photos site.

The tag on the stringer is not a HIN. It was CC's serial numbering system before the USCG developed the standardized system in 72.

If you have a Riviera with a 318 Poly engine, I doubt it's anywhere near a 72.

The 318 Poly was out of production for around 5 years at that point, so if it's a Poly in a 72 something ain't right.(like somebody slipped an old engine into the boat or the boat may be a 67 or 68 or so at the latest since the engines could lag the model year by a year or so)

Maybe it's a 318 LM, the marine version of the 318LA which went into production in 67

I don't know what years the early Riviera was made by CC, but I don't think it was still around in 72.

In about the 70 to 72 years, before the HIN became law, the ID tag was most likely by the throttle, not on a stringer like yours. Another reason for it to be pre 1970.

How legible is that tag? It seems to have one too many digits in it.

Maybe TRBenj will see this and have some info to add.

Steve,

Yes, you are correct that prior to the 70's and prior to the HIN's in 72, CC ID'd their boats with a simple aluminum tag nailed to the port side stringer next to the engine. They used a alpha numeric system with the first letter(s) being the model of the boat and then numbering which was a numerical sequence. In your case, the leters would be "AT" for Al Tyll Skier. Before the 60's, they used a engraved ID plate that was fastened to a hull port side frame or inside the dog house (engine box).

I'm going with it being a 1966

It sure is. 

You might have a hard time figuring out the year without getting info from the factory (Art Cozier who pops in here sometimes can dig through old records and find build info, but the virus has impacted his ability to just show up and do it I think)

A search here on CCF in the For Sale and Diaries sections will find a couple of Rivieras with their tag number listed.

One is a 67 ........tag number 1069

Another is a 67 tag number .........20164

Not much consistency between tag numbers

Assuming they knew what year theirs were, you can probably figure yours is a 67 at the latest with your 20149 number

Kinda interesting, the only ones that are in those sections or that are mentioned in threads about the Riviera are 67 or 68 models with a fair amount of guesswork in those threads, before the name was resurrected again in the 80's for a short time. 

I guess you could say it wasn't the most popular model they built 

What's the camshaft issue you're having ? Maybe trying to find an RR 318 Poly camshaft

The cams will both slide into your engine and have the same firing order, but the difference is the arrangement of the cam lobes/valves so one won't work in place of the other

On yours the valves are arranged   I E I E I E I E.

On the later LM engines they're arranged   E I I E  E I I E ( they borrowed a page from the small block Chevy design book) 

I don't have a clue where to find a new 318 poly Reverse Rotation cam these days but you might try these guys in the link unless you've already  talked to them

or here's a link to a FB page  for poly engines, maybe you could ask there
