cam selection

I'm no fan of MP. But...if the price is right, the 268/272 cam would be able to do what you want, and the 284/484 can be sold pretty easy. If they are both brand new in the boxes. If money isnt a big deal, or either of those cams are used, I would upgrade to something designed in the late 90s or 2000s. MP hasnt come up with a new cam design for Bs or LAs since about 1984.
