Getting ready to start round 2, and getting a shopping list together. Was leaning toward the Rollmaster timing set, but then I read this post

http://www.bulltear.com/forums/viewtopic.php?t=5752&highlight=rollmaster

I'm having a hard time understanding how the Rollmaster would hurt oiling to the front components. Was talking to Fuzz, and he even sent me some pics of both types of Rollmaster setups, with the Torrington bearing and without. Don't see how either would cause any problems. Am I missing something?

The blower engine has one and I'm sure you have seen the vids, I like it. Although for whatever reason I had to use 4 degree retarded slot to get the cam timed straight up. (again one of those things you have to do without thinking it to death.) Rollmasters good quality. I didn't use the thrust bearing however, I just have a hydraulic cam. I inspected the Rollmaster cam gear before assembly to check the oiling groove and I must say it was absolutely correct in alignment and free of any burrs. I had no work to do there.

I emailed RollMaster about thier timing sets.
They said that originally they made one without the bearing
and had problems reported with wearing the front block face
so they discontinued it.
They now offer only the Torringing bearing style
and there are no issues with it and distributor oiling.
I guess the Torr Brg has a larger O.D. than the front cam journal
so that the Torr Brg contacts the front surface of the block
instead of the aft face of the gear itself, preventing possible wear,
yet the torrington bearing does not affect dist gear oil delivery.
Not sure how they accomplish that, but apparently it works ok.
From what others said, guess it can be installed without the bearing.
Have read where others said it is very hard to remove once installed
due to the high tolerance tight fit on the cam and crank shafts.
But I have not actually had, installed, or used one myself.
Sounds like a good high quality piece from what others have said.
So I guess I was just flat out wrong in raising the Dist Gear Oiling question
but didn't get an explanation of how it's accomplished.
I guess the bearing works like any other oil system restriction,
"consumes" a minimal amount of oil, and still feeds the dizzy.

Hey Fuzz, how bout posting up those great pics you have.

Jeff, when you mentioned you had a hydraulic cam, were you saying the Torrington bearing timing set was more for solid cams?

The Rollmaster has a recess in the backside of the gear that runs the whole way around the gear, rather than just the little "divet" that most gears have that are "supposed to" line up with the oil hole in the cam journal.

[b]Yes the solid or rollers can walk more so it's more of a necessity than an option. If you want to spend more money and get the thrust bearing thats fine, your not hurting anything. I chose not to just because I'm me.

Yes they do.
