Gear-to-Gear timing chain ?

[triplecreek]

Iam sure someone has installed one on a 351m. How did it sound? Worth the money? Would you reckemend something else? Sorry for all the questions?

There are two types of gear drives, noisy or quiet. If you have ever heard a noisy gear drive they all pretty much sound the same.

Other than the noise there is no real benefit on a street driven truck for it over a double roller. They sound cool but won't make it go any faster.

Cloyes makes a gear driven timing set but not sure about for the 351m. I have been told that more vibrations are transfered from the crank to the valvetrain when using this design over a chain or belt. Dont know if there's any truth to that or not. I have never heard the sound that everyone speaks of, but it must be cool, and would be interested to hear.

The GM 2.5 liter "Iron Duke" engines I used to own all had timing gears, and they always had the same distinct hum. You can line up ten different 4 cylinder engines with one Iron Duke thrown in, and blindfolded I could pick out the Duke every time. For whatever reason, that sound has stuck with me.

The old 406 International Red Diamond six that I have now has a subtle but unmistakable whine to the timing gears. Kinda neat actually, when combined with the almost nightmarish rumble of the exhaust.

I had one in a 400. I got tired of people telling me "sounds like you have a bad power steering pump". I wouldn't put one in with out degreeing it in.

What do you mean by degreeing it?

Degreeing the cam into the crank, to the cam mfgr's specs. I've put a few Pete Jacksons in and they always have come up retarded somewhat.
