Barney Thank You for the brand but I was more concerned about the type of metal compatible with this cam. Cheers

well the crane gear is melonozed . a melonized gear is compatible with all cam materials. this way there is no need to guess what the cam is made out of but that "should" be billet steel. composite and bronze gears are also compatible with billet steel.

No hydraulic roller cam is made out of billet steel. Only solid rollers. You can use any good quality steel gear or the new composite one's which I don't trust. Your cam spec card should have it written on it the type of gear recommended. Do not use bronze gear with hydraulic cams.

No off the shelf HR cam are on steel billet, though custom ones generally are, comp will grind them on a -9 steel billet if you ask. The composite gears are ok but they do break, they are originally made to run in dry sump race engine where there is no oil pump load. Generally off the shelf HR's are made from selectively austempered ductile iron, which is quite hard unike normal cast iron flat tappet cams.

drill a hole in the gallery plug behind the gear and use a melonised steel gear and it will be fine.

As you can see by dwaynes post, some definitely are, but typically they are not.

And I bet there is absolutely zero wear on that crane gear i had you get...although the engine probably only has around 12 kilometers on it.  :lmao:

FYI - ALL off the shelf trick flow hydraulic roller cams are made from billet steel cores. It is one of their "claims to fame."

Clevelands come in two different dizzy shaft sizes. Maybe that's what hatzi is referring to.
As for billet steel hydraulic roller....it's an overkill and total waste of money. Hydraulic rollers generally only run half the valve spring pressure compared to mechanical so no need to be billet.

ok, lets try it this way;

Is there currently a gear on the distributor?

If so, is it new, lightly used, or heavily used?

I went thru this finding a gear that would fit fitzy's chinese distributor, and if I recall correctly, the shaft on it was not exactly the same size as a factory ford which is why i posted the little laughing guy in reply to jimmy's question.

It's a lightly used Pertronix II distributor and cannot find what type of gear is on it, whether it is suitable on need to change it. Cheers.

Did you drill a hole in the lifter oil galley plug like shaun suggested?

What oil are you using?

To get the distributor to fit just grind the end of the shaft down, works a treat..  :lol:
