nothing but trouble!!!!!!!!! We installed 2 on 2 engines same time . both broke snap wrings on the idler gears blew 1 engine and saved the other when we changed oil and part of the snap wring was on the magnetic drain plug, also had two of the procomp rockers broke which we caught in time. Word of thought, any part that starts with pro I would leave alone. I dropped 3 valves and trashed a brand new set of there heads, were thinking there valve springs were junk. LIVE AND LEARN .

I've been running a Pete Jackson gear drive on sustained high rpm highway cruisin for 2300 miles and so far so good!!!

There were three schools of thought:
Go chain a gear drive will fall apart on the street?
My roller rockers will loosen up all the time?
A few people said the pete jackson is a good unit and will hold up fine?

Pro comp spiral 10.5 mm cables work pretty good. No moving parts.

That is probably true, just don't use anything important that has procomp on it. As for gear drive I wouldn't run one on the street or for race of any brand.These were on strictly drag cars

Biglo said it....
I have 16k miles on my gear drive, roller rockers, High vol/pres oil pump and a few other items rumored to be not streetable.....oh yes 8k on the last oil change and analysis was very good.

Roller rocker have not been adjusted in at least 12k miles. No stud guides however.

Can't speak for the Pro Comp product but I installed a Pete Jackson gear drive several years ago. I didn't have any driveability issues other than the fact that the noise drove me nuts. I didn't think I was going to like it but installed it anyway. Be sure you're going to be ok with the way it sounds before you install it.

Mine wasn't the real noisy one but you could definitely hear it. The blower and drive made noise too and drownded out the gear drive . Now with lots of miles the whole thing has quieted down....maybe I'm just used to it.

I do like the noise, i have a cloyes noisy gear drive in my 64 bel air. Just was hoping to get a gear drive for half the price. So you have a pro comp gear drive BentWings? Would you guys still use it? Could it possibly be THAT bad of a gear drive?

You get what you pay for. I never skimp on tools, and I never, never skimp on the parts that go on my car. Just curious, where would you feel that is okay to put a cheap part on your car besides the cam drive? Suspension bolts? Seat belts? Connecting rods? Maybe windshield washer fluid, that's the only one I can think of. C'mon.
