1965 Riviera Identification

I have a 1965 riviera with a 465 Wildcat 465 Air Filter, so should be a 425 cui LW engine.

But the engine production code # is "K......W....518"
Engine serial # "7k1199047"

Anybody can tell what kind of engine this is?
Is the engine serial normally identical with the VIN ?
Mine is not.

For Pontiacs there is PHS as complete identification service based on the VIN.
Is there a similar source for Buick?

Thanks
Andre

231 V6, the engine serial number is on the front of the right cylinder bank
260 V8, the engine serial number in on the oil filler tube on the front of the engine.
400 V8, the engine serial number is located on the machined face of the cylinder block, below and in front of the right-hand cylinder head.
On most 1975 and later engines, the production code number can be found with the engine serial number.

Thanks Bruce

 

7=Series (Riviera), K=Year (1964), 1=Assembly Plant (Flint Mi), 199047=Production Number (sequence).

So it looks like you have a replacement engine. In 65, the Vin coding changed and only the last 8 digits of the vin were stamped on the engine and they were coded differently.

Yep,,, 1964 year 425....right color for that too.....

 

thanks so far !

So as the 425 (340HP) of 64 is identical to the 425 of 65, according to my information, not too bad, or?

How can I find out what my car originally has been, 401, 425/340HP or 425/360 ?

For Pontiac there is PHS-onlinedotcom as source based on VIN.... anything for buick ?

 

I "think" only a GS would have came with the Super Wildcat motor.

 

Not for pre 1970 models.

 

The Riviera Owners Association is a great resorce for answers to questions about production and other info.

rivowners.org

They sold 454 non GS Rivs in '65 with the Super Wildcat

 

If the original owners manual is in the glove box, there will be engine information on the last page or perhaps on the data-plate (if so equipped)

The single four barrel 425 (LW) was the least produced engine for the '65 Riviera. The standard engine was a 401 (LT), the next highest production was the super wildcat (LX).

Check the ROA's website for production numbers for each year. www.rivowners.org

I cannot find the engine code on my new 65 Riv. I believe I have a 401 but still have not been able to verify.

 

Here and here.
