OK, I know this is a dumb question but whats the difference and what machine work would need to be done on a 454 to use one? I'm thinking of switching to a roller cam and heard one would need to be installed.

Thanks

No machine work whatsoever, of any kind, is required.

You just buy the timing set with the cam gear already set up for it. Comp, Crower, Crane, & others offer timingg sets with the right stuff.

As far as using a roller cam, all you need is a cam button, between the nose of the cam and the timing cover.

You don't really "need" the thrust bearing, although of course anything you can rollerize is probably a good idea.

RB.. Please educate me. I have never seen one of these torrington bearing sets. What captures the bearing? Since the cam does have some endplay, what keeps the bearing / washers from falling into the oil pan?

I acutally am using a Dyna Gear set, has the torrington bearing allready machined and installed into the rear of the timing gear. It also has ±4° adjustablility in 1° increments.

Novadude:
The bearing can't fall off, because it's around the cam journal, and between the gear and the block.

I have one in stock, but I don't have a good way to post pics on this site.... I'll see what I can do to get you a clearer explanation.
