Looking for a set of Crane 741 cams or Merc 525 EFI cams. Let me know what you have.

You could use a Gen VI timing set with your MK IV block to run the 525 cam. That's what I'm doing with mine.

Did you use a retainer plate as well... Right now I'm using a button in my current roller set up?

I'm looking at the part right here in my office...

It uses a single roller chain and gear set with a retainer plate. Comes with the plate, bolts, gears. Bolts to the same retainer boss on the MK IV block that is used for gear-driven timing sets used on HD trucks. All 454s have the provision. I think I paid $50 for the whole thing off of eBay.
