    Is it possible to drill piston cooling nozzles in a DDEC 3 block? If yes, how to get it done? Has anyone done it ?

    From what I understand, at some point, the DDEC3's are already drilled, but I do not know what serial number they started drilling them.
    From what little I have gathered there is also some upgrades to the roods and pistons themselves in the DDEC4's that makes them stronger too, so am not sure how much a guy can really gain by just adding cooling nozzles. I really ned to do some more research on it, not sure why though.

    Some place in 2000 you can get drilled rods too. Oil passage from crank to wrist pin. Money well spent. Depending on what piston you have.

    heres the deal, i was told slap in a bk kit into a gk you dont need to change anything.. i changed the connecting rods and not like my mechanic knows any better and doesnt tell me the gk pistons were cooled rod thru, i put the bk connecting rods with the overhaul kit and now obviously the pistons arent being cooled, so i need to do something about this.. is it possible? has anyone done it?

    I can't answer , but am learning, or at least trying to. What is bk and gk?
    From what I gather,you used ddec4 rods and pistons in a DDEC3 block, am I understanding right.
    If that is the case, I did not know the DDEC 3 cooled through the rods, I wondered how it was possible to not have piston squirters.

    Some GK had nozzles, but did not have drilled rods. The BK after sometime 2000 got updated drilled rods maybe others idk. I have rebuilt one GK to BK. Added the rods. Nothing fancy but changing parts.
