Gear drives Of course the search is acting up right now..I'm wanting to put a gear drive on the 454 I just got for my boat. Has anybody had any negative issues with running one? I've always just used double roller chains in the past, but am leaning towards throwing a noisy gear drive in while I have put a chrome timing chain cover on.
I hevent really heard of any bad things about them, except on computer controlled engines it will mess with the knock sensor, since yours is carbed i wouldnt wory, i have put a noisy gear drive on a 73 camaro once and is was so load and annoying he wanted it right back off their soposed to sound like a blower but they dont.

Just asking, but why would you want a bunch of noise.
Best is a jessel belt drive, or get a quality true roller. Gear drives are a waste of money, and noisy ones are lame. My opinion only.

I don't want to spend $800 on a belt drive. I'm not worried about harmonics too much b/c this motor is going to be rebuilt eventually when I put the turbos on it. I doubt I'll even be able to hear the noise with the open headers anyway. With the gear drive and eventual turbos, there should be plenty of whine.

I had a jessel belt with 750 pass' on it. It's still in the trailer as a spare. It had 0 stretch on it. Only reason I bought a new one was because the block blew apart, and I didn't want to be cheap when building a new engine.
If you want cheap, get the best true roller you can afford. I know many guys running in the 8's with a chain. None of us use gears around here. Not worth it to us, I guess.
I would not lose sleep over a good chain.
1 ?? if the engine is so noisy anyway, why buy a noisy chain, they make it noisy by machining the gears a little off to get the sound. If you actually like gear drives, get the precision gears, not the noisy ones.

The gears are just ground with less of an angle to get more sound out of them. A little more straight cut I guess...I've just always wanted to run one for some reason. I have a new one for a SBC at home that I never used and am trying to sell. Just wanna do something different for a little while I guess.
i ran a gear drive on my last motor and i had no problems with it, i lost MAYBE 2 HP over a chain, belt drive is the way to go, but not everyone can spend the big bucks on everypart.
I have a noisey Pete Jackson gear drive I'll sell for $100 plus shipping if you want it.
It has about 5 hours on it tops.
Took it out while fixing a timing cover leak. It really wasn't that noisey unless it needs to break in or something.

I built a 377 for my old 68 Impala with a Weiand 177 and a noisy gear drive. You could hear that thing whining over the exhaust from two blocks away.

I ran a gear drive for a short period of time when I put my 454 together. It was so annoying that I couldnt stand it. IMO a gear drive shouldn't even be on the market. They cause huge harmonics problems + they sound like ****. They don't sound like a blower at all. In fact they sound more like a bad bearing in an Alt. or something. What good are they ? Either use a chain or a belt.
i loved mine it was the jackson quite but i was kinda loud at high rpms, i had a problem with the aluminim timing cover just had to grind it out but othere than that it was cool lol and everyone would ask "do you have a supercharger" lol it was in my 327 in my 80z28
