Gear drive timing gears
 

Is anybody here running Gear Drive Timing Gears in there 302? I am really interested in doing this, because i love the sound. But i want to hear ppls opinions of them.

I have heard ppl sat that the difference between the noisy one and the quiet one is just that the noisey ones have more slack and are more prown to failure. Also, i have not been able to find any single idler sets. Only the double idler ones, and have haear some storyies about these as well bein that as they wear they get sloppier and sloppier

What are your opinions of them?

I don't have a set yet but I will have very soon, and the noisy ones are tight just like your rear end when they dont have the proper shims and they Howell, I myself havent decided on what I want noisy or quite since I want to still hear my blower.

I'm ready to buy, Ive been looking at the edlebrock acue drive, but also there are lots on ebay, There is a company selling a set that looks identical to the edlebrock ones. I'm wondering if there the same.

the noise is cool but I would check to see if they will fit behind your front cover stang illusions. differant than the older cars?

Im planning on installing these on an 86, do you think that would be a problem, I was told that there is an acui drive kit that will fit. What year do the covers differ?

I guess they are a dual chain stock, so how would the gear drives be any different??

some of the older kits required the front cover to be moded this was a long time ago new ones might not? that car will sound like it coming apart gear drive and a blower

OK, I was told this from a very knowledgable cam grinder, this is NOT from first hand experience, but simply advice from a professional that I am relaying for you:

STAY AWAY FROM GEAR DRIVES.

They create harmonics that cook bearings.

The only difference between the loud ones and the quiet ones is that the quiet ones have helical cut gears, the loud ones are straight-cut.

Hopefully that helps.

Thats what I thought the diference in the gears were. I work at Toromont, and CAT has patented there gear design. There are a lot of differences in gears, i didnt think they could just be sloppier. It sounded stupuid, but i read it on some Camaro forum. Thanks for the advice. I dont really see how they can throw off the harmonics however. they would work on the same principle that a roller chain gear would work.. if anythin i would think that a chain would throw off the harmonics becase of variances in the links and them flying arounf the gears

i will have to do some more research thought, thanks

Well, my take on it is:

The gear-on-gear contact creates harmonics as the teeth strike each other, this vibration rings your motor like a tuning fork but really only causes issue at high RPM, which is where the "ringing" would be the most prominent.

The chain acts as a damper because of all the links, and so the harmonics aren't created.

The least harmonic forming method is a belt drive, like a Jessel, but those things wicked-pricey.
