I am with beater and cnc. The rods can't possibly be worse than a 235 rod and i have buzzed them to 6 k on a very very few occasions. And I don't ever remember hearing that packard used poor materials in their motors. Rebuild the rods and see if an arp rod bolt can be used. Good pistons, yes, you wont be sorry. Head work yes. Cam, you might consider giving Jerry Cantrel at Schneider cams in San Diego a call. He has ground my last two 261 chevy cams and was very cool to deal with and has been in the biz a long time. He should be able to sort out a grind that will work out. Unless you come across a vertex mag for the motor, I will guess that there are not to many options. I just used bubba's hot rod shop to rebuild a distributor for me. He also does custom work and is not a million dollars. He gave good advice and did a great job on my distributor so I would guess he would do the same for you.
