I just got a reply fom Comp Cams. They said DO NOT use the Crane steel gear. It's not compatible with their cam gear material. RAY

Are you running a street solid roller or a race solid roller?
Comp lists their hydraulic roller cams and certain street solid
roller profiles as being compatible with OEM cast iron cam gears.
I called Comp to discuss this and the tech I spoke with (Dennis)
said their -8 part number hydraulic and street roller cam cores are
austempered ductile iron. A surface treatment hardens the cam lobes
so they can run a roller lifter. He also said either a cast iron or
cast steel distributor gear is compatible with the -8 cores to run
with the cam. Not compatible are machined steel gears like the Crane
351C part which is made of 8620 steel, the same as a solid roller
gear. He said the OEM and Ford Motorsport steel gears are a cast
steel and would work fine but Ford doesn't make one for a 351C.
Solid roller cams are usually ground on 8620 billet cores and require
bronze distributor gears. It may be possible to use a machined steel
gear like the Crane (though Mike Trusty had trouble with his) but not
an OEM cast steel gear.

Has anyone determined if the composite gears are available for SBFs (in place of the bronze)?

Dan,

I just got off the phone with comp tech and they told me that the cam I have requires a bronze gear. The part number is 34-710-8 and he said it was a billet core not austempered ductile iron. Hummmmm, has me wondering if maybe some are iron and some are billet even though they are -8's.

And one rusty 64 Fairlane nick-named the Rust Bucket....And sometimes called the Money Pit...

The person that answered my e-mail was Darrell Miles. I gave him the link to Crane Cams gears. I gave him the info from my cam. Part number 32-771-8. Grind number FC288R-10. Serial number MB1991. RAY

I had to call Comp three times before I got a consistent story. The first two guys didn't have a clue but the third guy seemed to know what he was talking about.
