Solid Roller lifters

I was told it was a mopar performance cam. I got it from whitepunknitro and sent it off and had it reground to a .519 .531 I believe. If I need to upgrade the pump shaft I will. No sense in taking a chance. So the brass bushing comes out huh? How the hell do you get it out without dropping the pan again and flipping it over and punching it out? Ill do what I gotta do to preserve the build.

Maybe someone knows something I don't but I don't know why you'd eliminate the brass bushing. It's there to locate and stabilize the pump drive
