My 427 is almost done and I need my dist gear. What are you guys using and where did you it?

ng8264723 I got a gear though a friend that is composite. They are not building them yet. Comp is the one to ask. You want a gear that matches your camshaft material. Rick L.

why composite? i use a bronze with my roller. avail at keith craft racing

[Tim Brewer]

Composite will outlast bronze, bronze does wear out faster than steel.

[FWB]

sure bronze wears faster than steel.
define composite.....thats kinda generic for anything, what material?

[RICK LAKE]

FWB It's a magic material that just doesn't seam to wear. If the mix of the material is to hard the gear breaks, same for too soft. 2 yearson the shaft on my distributor and no wear. I had a steel gear on for 9 years and also no wear. I have oil leaking on the location between the to gears where they meet. I also have only .003" of end play for the cam shaft. This also stop alot of wearing on the gears both camshaft and distributor. Oil to this location and the timing chain extend the life of both 50% longer and cool the parts too. Rick L.

Personally, I think this is another area that removal of zinc from the oil caused problems with. Run a stock iron gear (not steel) and keep your zinc level where it needs to be. Like magic it won't fail just like 20yrs ago...

A stock iron gear on a billet steel roller cam will wear out in just a few hundred miles.

it's magic ? comon rick, hehehe, it can't be that magic somebody made it.
i will agree the bronze wears quickly, i have my dist. out now, 4500 mi on build and i may get another 1000 out of the gear its getting knife edged already. the MSD billet dist. i have is getting replaced by a duraspark unit, so there is a new gear in my immediate future. i take the iron will were out in a couple hundred miles to be conjecture at best.
factory cams were made from a 8620 steel blank, i would think this is a harder material that current roller cam material. some background for those who don't know 8620 from a wingbat...8620 was used in rifle recievers, ever try to machine a M-1 for a scope.......its like granite. so i am thinking to go with a iron gear. i think the quality of the helical gear means alot, if the gear is machined by a bufoon then its going to fail. i guess some investigating on my part is in order.

FWB I will call and ask. This is a private company that sell to companies like Comp cams. It is magic, the powder is poured into a mold and a 100 tons od pressure applied to make the gear. There is a 2-3% fudge factor they have to work with. I will try and call monday, if it's ok I will e-mail you monday night with his answer. Rick L. He will explain just how the MAGIC works.
