So I'm using this cam Howards Camshaft 221275-10; Hydraulic Roller 1200-5600 for Ford 221-302/351W SBF on my 302 renegade head roller engine and would like to know what material for gear on distributor before I install, Looking to use my Pertronix II billet dissy which is on my 289. Cheers Jim

i only use the crane gear when it fits the dist shaft.

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.

:agree:

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 The composite gears are ok but they do break, they are originally made to run in dry sump race engine where there is no oil pump load.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 unfortunately, not all the mfg's that make composite gears state that which hey should.

:agree:
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:
-
Thanks for the good info now is there a supplier for this melonised gear and are all the distributor shafts the same diameter? Cheers Jim

Here's a billet steel off the shelf ford racing hydraulic roller cam.

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.
-
Okay found out it's steel on the one I have am I good to go or purchase a melonised metal one.??????

It is fine to use the way it is.

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:

Then superglue it in place. :lmao:

Barney the engine has not been fitted in yet I'm thinking 10w40 semi synthetic and I may look at the dissy gear that was on the block originally off EL falcon with roller cam. Thanks for the tip Fitzy i' fly you up here to do your work.

i would run full synthetic like the 10 10ths stuff. i hope you have a one piece rear main seal.

He's pretty good with a bench grinder now! :bolt:

...and so is his ex "professional" engine builder. You should see the incredible job he did on fitzy's purportedly brand new distributor to get it to clear his intake.
OMG...I think I justn peed my pants!

With that possessed car, I wouldn't be climbing under it!!!!!!!

hi Folks
My general rule is steel cams need a steel gear cast cams need a cast gear, I put that question " can I use a cast mellonised gear on a steel billet cam?"to a cam manufacturer recently and they replied, no you should use a steel gear, and the cam manufacturer was Camtech Cams.

They need help. A melonised gear is steel, and yes, you can most certainly use it on a billet steel cam, at least you can use the crane one on them just like a bazillion other people have for the last bazillion years.

Yeah those ancient cavemen swear by mellonised cam gears :grin:

You forgot to mention to grind the housing away for intake clearance too...or maybe that was for additional cooling. :lmao:
