Projects 1955 poly engine

I have a p27 engine block

Is this a 241 or 259????

Also still needing a exhaust manifold. Casting number 1553784. Look at the pictures below


Thanks

The bolt pattern does not match the Hemi ones

 

Does not match!!!

 

the 241/259 were basically the same motor....where we come up with the part issue....is it is the left side which concerns the steering box.....the Hollender says...55 Dodge/Ply - 8.....56 Dodge/Ply 270 which is a poly motor....join the HAMB 55/56 feed....sure to find one there....

 

oh....and I think the right side works for more years.....
