JrFuel Hayden:
A cup holder, is that for Coke, coffee, or beer ?
I hope my sugestions are not out of line, our team is always looking to run quicker and faster, and you look like you want simpler bracket racing.
Have Fun

Are you using a bronze gear on the distributor now? Might look at the material compatibility of your cam gear and the distributor gear. A mismatch of materials could lead to excessive wear. Or look at this oiling solution; simple, inexpensive, and appears easy to do. About a third of the way down the page, they are using a billet cam with a stock 350 cam gear.

Looks like the server is down on the site. Here's the pictures. A section of 1/8" copper tubing was run from a pressurized oil galley through the front cover and pointed at the gears. The poster said it cured his wear problems and that the 0.040"-0.050" hole in the end of the tubing didn't reduce his oil pressure.

suggestions are not out line. my background is/was(retired now) a r&d/experimental machinist at pratt & whitney jet engines. I can't afford the jet engine material nor have machines to work the material. if I did, it would be one heck of an engine. so any I do is like a never ending science project with a buick 350. a lot of parts on the engine are/were not designed for a buick 350. it's become more of a Frankenstein as most people call it.
microblue or rem is metal finishing, the idea is similar to things done to jet engine parts. a lot of ideas in other avenues have been used in our racing world with success. I figured I would asked if anybody has any knowledge of it. if not, I will be playing guinea pig with it. hopefully it works.
the bronze gear symptom is an issue for the buick engines. stock engines will 300k and not show any wear on the two gears. as soon as we start adding h/p which we have to add oil pressure do we have a gear wear issue. we also have an issue with cam walking. the v6 can be helped with a plate, but the other engines cannot. the idea of going to a dry sump is tough for me. the 1968 chassis rails and the buick engine offer very little room for anything. I would have it direct drive off the c/shaft which would conflict with the stuff already there. but because this is how we run the dragster, we sometimes end up with some pain in the butt problem. but we and the engine have survived w/o being apart for the last 5yrs.
we chug along at 9.2's at 145 using a 4-71 with a 650 holley. looking to go to a roller cam for next year and see if it will make it to 8.5.
that's my story and I'm sticking to it.

roger, there is a thread going on the v8buick site in the 350 section about gear wear and some ways for a possible solution. but they are not a 100% cure.
