[QUOTE=SB;4397357]I thought the later tall risers got rid of the reversion on the HP500 ? They are pretty damn tall.

I remember a heat treat difference between those breaking and not, but can't remember if there was a core difference.

Not sure the material but they were the cams that had the black color inbetween the lobes. The gold ones were the good ones.

The ones that were black in color were were breaking. The copper colored ones were not breaking.
Don't know the specifics on the different cores that were being used.

Funny thing is the 5150 is actually a better base material than the 8620. But due to the difference in material requires it to be induction hardened rather than oven baked which is more controlled and yields a better finished product.

Call the manufacturer and if they don't offer that service I bet Stainless Marine will.

A custom cam does not guarantee that it will work, or work better then an off the shelf cam. Even if it does will it even increase the boats speed or reliability or just make the owner feel warm and fuzzy inside due to the hype.

There's a LOT of R&D already put into off the shelf cams.

But custom cams are cool just not for everyone.

What I enjoy are these threads helping fellow members look at multiple options!
