1st Gen number help.


Recommended Posts

Hey guys,

A little while back i went to look at two Rivieras that were for sale and the owner was wondering what year/size the engines were. The vin numbers didn't match those on the cars and he asked me if I could post this for him so he could give potential buyers more information. I could not see the engine code on the front edge of the block just the VIN numbers.

1st engine 7k1024083

2nd engine 7J1088711

Here's the numbers you need for cubic inch identification.


The engine production code number is the one you're looking for; one of two letters:

T=401, W=425

The 7K is a '64, the 7J is a '63. The former bolts to an ST400, the latter bolts to a dynaflow. If you can see the hub on the end of the crank you'll see that they're different. (J=63, K=64, L=65, M=66, etc.)
