Job Rated Dodge truck: What poly engine?

Found a Job Rated Dodge with a poly-head engine in it today.
It's got a one-piece windshield, if that's an indicator of the year.

What engine displacement would this be?

I helped my buddy pull one out of a 55-56? dodge truck the day hurricane irene hit pa. when he got it home and looked up the numbers he said it was a 241. hope this helps.

 

Here is some Poly info http://www.allpar.com/mopar/poly.html.
Hope it helps.

 

Look for the 'use code' stamped in the block.
First question is whether it has a separate valley cover or if the intake manifold seals everything.
A separate valley cover indicates it is a Hemi-based poly and the id will be found on the top front of the block, ahead of the valley cover. The other will indicate an A series engine (like a 318) and the id will be stamped on the front of the block just below the head gasket on the driver side.
The Hemi-based poly id numbers are on my web site.

.

 

TR Waters has posted pics of truck hemis & Polys with the use code there also.

 

I went back today and forgot to look for the code on the engine.
It's NOT a 318, that much I know (separate valley pan under the 2bbl intake)

The block doesn't have the extended bellhousing, if that helps further.

Thanks,
-Brad
