I can't find that casting number in my books. There is a number on the block in front for the passengers head on a flat spot on top of the block. It should end in one or two letters which will tell you when it was made and the basic configuration i.e 2 or four barrel auto or stick etc. If you can get that number i can be of more help.

According to your VIN, your car was built in St. Louis on Friday, February 18, 1955.

I think maybe your block casting number is 3836233, instead of 3836288. That number indicates a 6-cylinder 1955 engine. On a 6-cylinder the date code is cast in the block just above the starter.

Appears to be. 0I6I394t55y
No, that is the engine serial number and suffix code.

The "T" denotes that your engine was built in Tonawanda, NY.

The "55" denotes 1955 Model Year.

The "Y" suffix identifies the engine as a 235 6-cylinder with Powerglide Transmission.

The "0161394" means that this was the 160,394th passenger car six cylinder engine built in Tonawanda with a Powerglide for the 1955 Model. They started the number sequencing at "1001".


In order to determine numbers matching you will have to get the Block Casting Number and Date Code. The block casting number is cast in the block forward and right below the distributor. It should have the casting number of "3836233" if it is a 1955 block, or "3837004" if it is a 1956-57 block. The date code will be cast in the block just above the starter. The date code will begin with a letter "A-M", with "A" representing "January" and "M" representing "December". The letter "I" was omitted because it was also used to represent the number "1". The letter will be followed by usually 3 numbers. The first two numbers will represent the day of the month, and the third number will represent the year. (i.e. "5" for "1955", "6" for "1956", etc.) Example would be M214, which would be December 21, 1954. (This would be for a 1955 engine).

Just remember that in order to be numbers matching the engine date code should be before February 18, 1955, which is the production date of your car. The engine date will usually precede the car production date by anywhere from 1-8 weeks before.

I would be a little careful of this statement.

Thumper generated the '57 production dates based on some internal memos on monthly production figures that were discovered and published. I haven't seen similar memos for '55, and based on checking date codes on my '55, I'm not sure the dates are quite as exact.
