Thread: 350 Chevy Geared Timing

Tweet

I've seen the geared timing for 350 chevy. I'm wondering if that would be worth the cost as opposed to a double roller timing chain. If they are worth it which brand is the best and and which brand has the best noise. What are the benifits to the geared timing as opposed to the double roller. Any info you have would be great.

Thanks

Gears are for noise ( they sound like superchargers whine ). Pete jackson makes a good gear drive, proform has one that is $93.00 if you cheap out. If you have a supercharger you dont need the gear drive. The most common and efficent way to time your cam is with a roller chain. Cloyes is a good company for them and they sell them in summit and jegs, these do wear out where as gear drives don't. when they wear out you just replace the chain. There are other company's that make roller chains but cloyes holds up for a $25.00 timing chain set. In gear drives, they are not as efficiant as roller chain but they all have about the same noise unless you get one that is " silent " these do not make noise.

Gear drives are designed for taking the chain slap out of the timing equation. On the street, all they are for is making noise. If you want the noise to be in "stereo", then run a gear drive and a quick change rear end!!! Guaranteed to drive ya batty after 100 miles of down the highway driving.......

As I recall, back in the 50s someone made a shiftable timing gear kit for small block chevys. The gear in the center, between the crank and the camshaft, could be moved back and forth with a choke type cable. The idea was to retard the cam timing for torque, and advance the cam timing for revs. I believe that it was originally developed for added torque to tow trailers through the mountains, but it made it's way to the drag strip.
If that is already common knowledge, bear with me, I haven't been around the scene for many years...LOL

I got a quick question regarding gear drives, so I figured I would post it here, I am building a 37 pontiac with a 350 chevy, I was thinking of running with a gear drive set up, I read the last thread with the guys talking about the pros and cons of them, but I heard that they sometimes cause problems with the cam cracking due to the vibration coming through the gears?? Is that true? Or is that only on real beefy engines?

Thanks, Jack

So I guess that means, I probably won't have a problem with it on my 37. Kool

Thanks, Jack

HA HA! thats a great point, I guess I will order one for the 37, probably noisy, just cause I think its cool, after all, thats what its all about, right?
