Hauss,
I too am in sort of the same situation as you.
408W with unknown internals.
While I was changing the intake I found I had a solid roller lifters, pointing to a Billet steel cam.
While experimenting with EFI awhile back (which I ditched) I came across a Timing hunting issue and discovered a lot of backlash in the Distributor rotor. Pulling the Dizzy I found a severely worn (knife edged) Bronze gear.
I didn't feel like pulling the water pump, Pulleys, Balancer, timing cover and timing gears to get the Part number off the cam though.
I contacted Comp Cams and Crower on alternatives to Bronze, such as Melonized Steel, or Composite. Both Tech lines recommended Bronze or Composite as the Cam was already broken in and could cause issues using the Hardened (Melonized)steel dizzy gear.
So I made the choice to stick with What I had. Figuring with Bronze if it made through the
oil filter it's mucho better than steel.
My eventual goal is to swap out the Solid roller for a Hyd roller. Pricey though as I'll have to change Cam, lifters, springs, Pushrods.
Contrary to to some of the posts in the thread, there really aren't squirrels scrapping the bottom of the
oil pan slinging
Oil and Metal all over the engine.
The oil pump does suck from the bottom of the pan and goes directly into the filter. I actually feel a lot more comfortable having my Bronze Gear being chewed away VS my expensive Billet Cam sending steel to the bottom of the oil pan.
I feel you've been Dog-piled with quite a few Non-helpful responses in your request for information which is unfortunate. I do feel Blykins and Gaz64 knowledge can be trusted as they are professionals in their field having "been there 1st hand" & not amateurs.
