Does the Lunati Solid Roller cams require a bronze distributor gear? I have both a bronze and a standard one, and Im confused.... :mad:

Depends on what core it was ground on. Most shelf cams are ground on a cast core. Many hi-po performance camshafts and special order camshafts are ground on a billet core. If you're using one with a billet core you will need a bronze gear. I've heard that some manufacturers (maybe all) can build you a billet core (good for longevity with heavy spring pressure/big lift) and press on a cast gear. That might be the best way to go.

Its not a shelf grind, its a 502A7LUN... They are grinding it for me as we speak :D

Call em & see if you can get it with the cast gear option.
If not you need a bronze gear or you can try the new Comp Composite gear for about $100.
I haven't tried it yet but have been hearing good things about it from cam manufacturers other than Comp which is usually a pretty good sign :D

Mike,

I can vouche for the composite gear. I have over 1000 miles on my solid roller 454 and when I took the gear out to take a peak at it I had to look at it very close to see any signs of wear. They are not cheap, but seem to work very well. I am telling you it looked brand new.

Since we are on the subject ... the Comp catalog states that the composite gear is not intended for use with a wet sump oiling system. Sounds like it is only designed to turn the distributor which is very little load, not the load of an oil pump. Will be interesting to see how they hold up in the long term.

Thanks, I had one but sent it back because my customer didn't want the be a "test dummy" for me :D

Bill,
That was what I was originally told too but they have since changed their recommendation to include wet sump depending on who you talk to.
I guess I will have to put one in something & give it a try.
