216/235 block casting number. Oddball number

This one has me stumped. I've got every number to decode a Chevy 6 from the 37's through the 70's. I've decoded a ton of them. This motor came from a 1 ton 47-54 Chevy truck. It has the 216 lifter cover and valve cover. Being that it is in a big truck I figured it was a High Torque 235. BUT... The numbers aren't adding up.

The number on the distributor pad is AHCA1018891.

I can't find this number anywhere in my books or on the different Chevy websites. Obviously it is a pre 53 motor because it has no side mounts or date castings by the starter.

Any clues?

 

Here is a pic of the number on the dizzy pad and the lack of a date code next to the starter showing that it is at least a pre 53 motor

Here is one site that shows a lot of numbers. It isn't complete though.

Anyone??

 

Inliners.org shows it is a 216 from 1950. http://www.inliners.org/becks/BCN2.html

Did you try looking at Inliners.org? They have a listing I think. I can't see the numbers in your pictures, sorry.

 

HAC means: 1950 Truck Series 1500 with a 216 P***enger Car Engine w/HD Clutch ***embled in Flint, MI

The next number is the sequence number of ***embly, starting with 1001 at each plant.
Not sure what the 91 suffix means.

According to the inliners.org link from above, the block casting number should be 3835497

 

Road Runner has it correct. Probably one of the last coming down the ***embly line for that model year. I have a first series 3100 with a stock 261 in it. How did that happen?

How do you know it's a 261? what year is the truck?

 

You guys nailed it. It's a 1950 216. Came out of a 50 3800 Chevy one ton. Finally removed enough of the grunge to find the block number. Roadrunner is correct on the casting number.


I had high hopes that is was a high torque block. Oh well. My goal of having one of every casting of pre 62 inliner is one step closer!!

 

There it is. Hidden under years of grime.

 

Interesting to find a 216 p***enger engine in a 3800 Chevy one ton.
So the A letter in front of the HAC indeed indicates that it was ***embled by the factory that way, according to the notes in the serial number link.

That engine must have worked hard in its day.

 

According to the resto pack
AHCA is a designation for a truck engine Flint plant
