composite or polymer gear for FE?

[poboy427]

I'm running a Comp cams solid roller. I was looking into buying a composite dizzy gear. They seem to be unavailable in .500 for aftermarket dizzy and also unavailable in .467 for FE though they are available for SBF in .467. I guess the difference, even though they share the same shaft diameter, is either the pin location or gear pitch??

Anyone know of a vendor that sells composite gear for FE? I mean, the composite or polymer gears as they are sometimes called, have been around for a few years now. You would think that these gears would now be available for FE.

It doesn't matter what kind of engine you have (FE), it's cam material and distributer shaft size, brand.You need to call Comp cams and they'll tell you what you need.

I THINK the gear pitch & tooth count is the same on the FE & Cleveland, but shaft sizes & oil pump hex remain different ( please verify this before spending your $$ ). SBF Fords 302 & 351 Windsor have identical tooth count, but different shaft & hex sizes. Check with some of the FE builders like KC, B2 etc to see where they are sourcing this stuff. I have assumed your running std pump & wet sump, If your using a dry sump then a good bronze gear will suffice as there is no pump load then.
I have always meant to look into swapping the oil pump gears for those from a 351 with 5/16" hex, enlarge the pump shaft spigot in the block & fit the 351 shaft into the FE dizzy to over come some of the issues, but the need has not arisen yet, but getting closer!!

Neither...

Run a steel gear from Crane or Mallory. If you tell me which distributor you have, I can give you a part number. I have the Crane gears in stock for an MSD...if you need one, let me know.

We use the Crane gears as well
Readily available in .467, .500 and .531 shaft dia

Use the steel gear. Install and forget.
Any bronze or composite will wear fast if you use a HV oil pump.
Or do you want to change the gear regularly?
