So why do I need a bronze distributor drive gear if running hydraulic rollers?
because the cam core is billet steel and needs the bronze gear and a bronze fuel pump push rod as mentioned.
on my SB the cam core has a cast iron gear pressed and pined on so the stock gear works.
my lunati roller cam runs stock roller lifters,push rods,rockers,retainers,seals with comp 901-16 spring = single with damper and no machine work,stock retainers/seals
done jerked it and stabed it in the 2nd SB engine with no worrys  on another set of roller lifters..something you cant do with a flat tappet hydro or solid.why I consider the roller cam upgrade as an investment 
i have 3 roller cams now and a couple stock ones for regrinds
lots more to the BB than a SB so the homework is key to longevity

A good read....my 505 has a few parts to finish collecting and its ready to go. I have a .541 lift roller cam from Comp plus roller lifters, a HV Melling Oil pump, the Bronze dist. gear. (But I have to change out that bushing), I have to get that fuel pump rod as well as all the pushrods, I have the cam button. I just spent the little money I saved and bought the Harland Sharpe rocker assembly. Matched with the Eddy RPM heads and swapping out the valve springs for the COMP recommended ones...I am hoping to own the beast she was destined to be. Hopefully getting to the goal of 550 realistic HP.

Sounds nice. What compression ratio and intake?
Just asking, I just started building my 505" stroker. Should be about 10:1 with stealth heads, and I am planning on using the comp XR286HR cam with Isky 8005A valve springs, because I plan to use higher ratio rocker arms, maybe 1.7:1?

11:1 with a CH28 Dual Quad and dual 500 Eddy's. I have the dual quad setup on my 440 now and LOVE it

The only downside to running a roller cam is cost.
Part of the additional cost besides the cam and lifters are valve springs, pushrods, cam button, and bronze distrubitor/oil pump gear.
With a big block maybe, smallblock not so much since the factory churned them out in huge numbers from 88-03.
All you need is the cam and new springs.
I picked up a used ($175) .505 lift Comp Cams roller for my 5.9 Duster and it dropped right in. Stock pushrods, lifters, cam gear and rockers.
Big block is a different story as there isn't any factory pieces to fall back on.

If you use a hydraulic roller camshaft you can use stock stamped steel rockers, just get the pushrod length right. Millions of Detroit hydraulic roller engines have been built with non-adjustable valvetrain.
R.
Really? No change of the big block rockers from stock non adjustable to adjustable? How did you get the dimension for the proper pushrod size, please? How is the streetability? Thanks!
I"m sure it could be done with a checking pushrod and made to order pushrods. The stamped rockers have limits on how much spring pressure they can take. They max out at about .5" lift. I wouldn't see the point in running a roller with such small lift. Might as well run a mild hydraulic flat tappet.

I believe you... some have run the stamped rockers at high lifts. I also know quite a few folks have punched holes in them with the pushrod at much lower lifts.
I speared new MP "6-pack" rockers twice on my 440 back in the day running a .509 cam and the recommended springs. You could not get me to run a .500+ cam again with stamped rockers for love or money with a big block.
The new Magnum small blocks seem to have no issues however, I know lots of folks running over 500 lift with them.

funny you mention that because if i DID still run the stamped rockers, my engine wouldnt have eaten a bunch of needle pieces and destroyed itself. They did work fine.

I sure agree with you on the needles. With a stout well oiled shaft MOPAR's don't need them. My favorite types are the ductile iron, Comp Pro Magnum and RAS. All simple, stout and robust plain bearing types when applied correctly. I'm running the Comps.

When it comes to roller rockers, in my opinion go with a part with excellent reputation like Harland Sharp or don't bother. Run them on the Magnum engines for thousands of miles without fail.
T&D also has an excellent reputation.
On the GTX I went with a set of Max Wedge rockers I stumbled upon and they are still on the car to this day.
