Engine ID help please

Hello from Colorado

1955 plaza plymouth

Engine # P27-217694

Try to figure out if it is a 241 or a 259

Any help would be appreciated. It has been on blocks since 1973..

Thanks,

Derek

 

If it has the 23" engine, my guess would be a 230. Derek

 

As you may already know P-27 was used for both engines. Might try the casting number, I'm ***uming they are different between the 2, if not you'd have to measure the bore. 241 is 3.4385 259 is 3.5625

 

I will be pulling the engine this next weekend. The number In the first post I think was the casting number.


Engine # P27-217694

Thanks.

 

That's the use code.

 

Where is the casting number located?

 

This is all I can find...

 

Casting number is on rear face of the block. I can't seem to find my ref with the poly casting numbers, not sure if 241 Poly has a different # than the 241 hemi. '55 Hemi would be 1632229 or 1635829

 

found it. '55 259 from engine # 60201 casting number 1630392

 

What would the 241 poly be?

 

Where is the casting number located again on block?

 

Rear face of block

 

my ref doesn't show # for PLYMOUTH 241, only Dodge so I'm not sure if polys & hemis have the same casting #. dodge is 1409528 or 1613745 but those are listed for 53-4 dodges
