I'm considering getting those timing-gear sets instead of a timing-chain. Anyone ever use the gears? Any good or bad experiences?

Timing Gears Instead of Timing Chain?

There was a guy who used to post here named Dave Wendland. His car is long gone, but he still has his website with a lot of his projects..... one of his best is a T-top conversion.
But he also installed a Pete Jackson "Silent" gear drive. Kept it for about a year and pulled it off, because he could not stand the noise. The knock sensor also will not function because of the noise and needs to be programmed out.
He had to machine the stock LT1 timing cover to clear the gears. You need an electric water pump because there is no water pump drive gear on the aftermarket sets. I'm not sure how the Opti responds to the "noise".... Dave was running an Electromotive Opti-Eliminator at the time.
There are supposed to be quieter sets available.
Just curious... why do you feel its needed? People have had good results with the LT4 Extreme Duty timing set, others have converted to a Cloyes double roller.

I would also question the use of a gear drive timing setup. They are extremely annoying. Sounds like the motor is ing for help. The Cloyes double roller is inexpensive and a good timing set. But, like Fred mentioned it requires the use of an electric WP. If you want to get serious, use a belt setup. The CC belts are very good.

On a 96 & later, he would have to do some grinding to get a Cloyes double roller in there.
I've been wondering if anybody fitted a belt on a LT1 - Has it been done? If it's the same diemnsionally as a Cloyes double roller, then there's no reason it wouldn't work. I need one, that's why I'm asking. Kev - do you know?

However, the true benefits of the belts are the inhibition of the transfer of crankshaft harmonics throughout the valvetrain and they take much less power to turn. In turn, your valvetrain will be much more accurate and depenable and you will free up some power.
