64 Riviera engine code location

[Markus64]

Hi guys,

 

i just bought a 64 Riviera that is equipped with the super Wildcat Option (Carter AFB Dual 4-bbl.). I want to check if the car was built with the optional KX engine or if somebody installed it later. I couldn´t find the KW (standard) or KX (optional) engine code on the engine. Can somebody tell me where to look for this code?

I think the first photo shows what you're looking for...

What did you find?  The only number you really need to look at is the Engine Serial Code.  If it matches the VIN, the engine is original.

Hi RivNut, 

 

I checked the code and it is a matching numbers car, but with the kw-code for the standard engine option. So there are two opportunities: 

1. Somebody installed two carburetors (Super Wildcat option) later or

2. I´ve read that some dealers installed the kx-option when the car was in the showroom, if the customer wanted to 

 

but I don´t know how to figure that out. Anyway it´s a wonderful car, which drives perfectly.

You could start by looking at carb numbers, intake casting numbers, etc.  Someone else will have to help on this one -- The '65 LX engine (A8 option) came with a distributor that was calibrated to be timed at 12 degrees BTDC instead of the 5 degrees on the JW, KW, and LW engines. I don't know if the 64 A8 engine had the same distributor or not.   If there's an aluminum band around the distributor look to see what the number is that's stamped into it.  The number for the '65 A8 distributor is #1111058.  The number for the 5 degree distributor is #1111055 

 

Your last sentence is the most important one.
