roller cam & dist gear question

I have a Mallory Unilite distributor for a 'Vette with tach drive.

I have read on Mallory's web site that the gear on certain of their distributors is already compatible with hydraulic roller cams. With solids they recommend a bronze I believe.

Anybody know for sure if they are compatible?

Check with the tech people from which you are buying the cam from.Normally,they say that with a roller cam,you should use a bronzegear.But there are exeptions :smash: :cheers:

My Crane Hyd Roller cam comes with a cast iron dist gear whihc makes it OK to use with the stock dist gear. I am running a MSD ProBillet corvette dist.

Re: roller cam & dist gear question (69vette66)

I got an e-mail from the Comp Cams tech and he confirmed that generally they look for the dist gear to be of a softer compound than the cam gear. Thus, the hardened alloy gears are o.k. with (most) hyraulic rollers and the solid rollers are not.

Also, the tech at Isky said all their hydraulics are compatible. And that on request they will "back-half" a solid roller to make it compatible. Which I believe means the somehow make the cam and then force on a gear afterwards.

Anyway, some intersting stuff to know.

Thanks, Mark

My solid roller has a pressed on cast gear so it is compatible with stock distributor gears. Most of the street roller cams can be purchased with a cast gear.

Re: roller cam & dist gear question (ZL1powr)

I have a comp cams Hyd Roller for a Gen V/VI big block and called comp and asked if I needed a bronze gear, they said no. So i kept the stock gear that was on my mallory unilite. So far so good.
