Why is it

[Blown 472]

that stock motors with roller cams can go 100,000 miles with out any trouble with the dist gear, but race rollers eat gears like crazy?

It,s not the angle of the dangle ...It's the bore of the ***** :D
Spring pressures and ramp angles:confused:

But seriously Blown, I dunno.
Speculation: When I put a 1990 fuelie 318 into my 1983 Ramcharger, I switched to a 4-bbl manifold. I saw the roller lifters and chain. All new motors have 'em...probably to help meet epa mileage requirements...
I guess they'll last longer in my case because I'm rarely above 3500 rpm and have wimpy stock valve springs.
Off the top of my head, that's all I care to speculate.

Probably because aftermarket roller cams are billet. And you have to use a bronze gear. Where the factory rollers probably have a cast camshaft and therefore you use a steel gear.
Seems the cam grinders were offering some options for a cast gear on roller cams. Thought it was comp cams offering that.
I use a Super Mag III. Hard on the bronze gears.:mad:

Oh...Blown was asking about the gears. I missed that one...:rolleyes:
