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 assuming 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
