I have a 396 that was pulled out of my truck (not original, truck is a 78 C10) . I was told it was a 1969 when we went to get it and that turns out to be correct. My heads are 1972 heads off of a 402/454.

My Block Casting number is 3955272, which is a 1969 396.
My partial VIN is as follows: 19_378285

The missing 3rd character should be a letter, most likely a K for Kansas City.

What I have figured out so far is that the 1 is for Chevrolet, the 9 is for the year 69 and the the last 6 are the last 6 of the VIN of the vehicle it was in.

The engine ID Code up front is T1226JK. I know the T is Tonawanda, the 1226 is December 26th, but I don't know what the JK means.

Anyone know that the JK means or what any of the 6 numbers on the vehicle vin mean? Some of the things I have read indicate the 37 means sport coupe. Any help would be appreciated, just trying to see if I can determine what the block was originally installed in.

Attached are some pics. You really have to blow up the second pic to make it out.

Looks like the JK means it was a 396/325hp with TH400
