I don't 'think' I do, I don't know... that's why I'm asking if it's worth it to do now since it's all apart and would be easy to take care of. That long drill bit is less than $20 off 440Source and I already have the HV pump which is the ONLY reason the thought even crossed my mind... Also something else to consider, I have a feeling this won't be the only life this 440 will live. Meaning my ultimate long-term goal for the truck is to swap a Cummins diesel in it, has been since I got the truck; I know I don't need one but I've always wanted one. Diesels are just cool and different. SO if/when that time comes, the 440 will be taken out and likely put into a car with a different cam and may very well be revved to higher RPMs. I don't know for sure but it would be convenient to already have oiling mods done if that ever becomes the case.
I think I'll drill the main bearing supply passages and clean up the inlet passages to the pump but still run a standard-volume pump. I like the idea of increasing oil flow by reducing restrictions in the system rather than bolting on a bigger pump. Nice thing being a BBM after all is the pump is external so I can swap it out later if I want.
