gear drive

how many here are using one, how long have you been running it, how long before you got tired of the noise even if you have the quiet version and would you use one again?

Re: gear drive

I installed one on a ford 351, the customer hated it after the first month and asked to have it replaced with a double roller set. It was louder than the exhaust (dual 2" with aftermarket mufflers) and quite annoying at freeway speeds.

That being said, I have heard them on third gens with cut outs and it was manageable at idle but may be irritating on the highway. IMHO, unless you need them, a good double roller is probably a better way to go.

Re: gear drive

Same here:

Back when I was building a lot of motors, I couldn't talk somebody out of having me put one in his project. Around 3 months later he paid me again to take it back out.

Kinda like Rhoads lifters... seems like a good idea at the time [/bullitt] but the welcome wears thin pretty quick.

Re: gear drive

I ran one of those floating dual idler noisy gear drives in my race engine for a day before yanking it back out.

I now run a Milodon single fixed idler in my engine. Rock steady camshaft/distributor. No noise and will probably last longer than the engine will. They're costly and after checking out belt options, I felt it was a better bang for the buck.

For a street engine, stick with a good chain system. At least pay a little extra and buy one with billet gears.
