please forgive my ignorance but I have seen people talking about long and short block for these cummins motors and I don't know what they are talking about. I thought all of our blocks were the same? Can some one please educate me on this?

 

Long block includes the head.
Short block no head

 

Short block is the block and rotating assembly. A long block would be a short block plus head, valvetrain, I'd imagine oil pump, water pump as well. Full engine you could add in the manifold, turbo, fuel pump(s), PS/Vac pump, etc.

 

thanks guys!!!!!
