What type of 440 is this? (Pictures)

I hope its okay in this forum.

Can you guys ID this engine for me?

I pulled it out of the Jensen to restore the engine bay and we decided to put a comp xe268 in with a dbl roller chain.
Engine has about 26K original.
Vehicle is a 74 so I am pretty sure that date code is 73.
The Jensen factory painted all the engines black after receiving them. So that's why there is black paint over Chrysler blue.

Strange Maltese cross on the pad near intake front.

9-12-73
