Less than 1000 miles on my Cryo treated Cloyes 9 Way Billet Chain and I'm about ready to throw it in the garbage. It's lost 4 degrees in less than a 1000 miles. It was originally 107 when new but now it's at 111 on the dots in its sloppy state. Now I'm 8 degrees retarded on the stupid crank gear that's apparently stamped backwards according to the instruction sheet just to acheive a 105 installed centerline. Still not the 104 I was looking for by advancing the cam. I think the only reason I'm not certain about swapping it out is that I'm not sure a new timing chain would last any longer. At least right now I can hope this dumb thing is done stretching.

Rant off...

Try Rollmaster.

Im currently running a Rollmaster set that I brought off Rebel about 13 years ago along with an Engle cam lifter and spring set, sure its been on the shelf for some time but that garbage got my sidewinder headed 446 goin real good.... real good. cheers Reb

Re-degree the cam and please report back in another 1000 miles...

Is the crankgear that loose on the crank? Seems to be quite a gap.

Rollmaster here . Had it for years.3 diff engines

I can't remember the name of the timing set right now (might be a Rollmaster?), but I got it from Dwayne Porter (Fast68plymouth). I got the good one from him after I had a Cloyes chain that started breaking links. Found it before any damage happened. Had a long talk w/ Dwayne and he said this was common w/ those chains.

pro gear?? i think from australia really nice piece mancini sells em.

KOS...now that I think of it, I think it was a Pro Gear. The Cloyes I had was in bad shape after 2 years. The Pro Gear looked great after 5 years...that was 2 years ago.

Pro Gear in my small blocks.

ProGear in my big blocks; Rollmasters didn't hold up well.

Chains don't stretch. The pins wear.

Sounds like your pins weren't hard enough, or getting enough oil.

Who sells the Pro Gear sets?

We killed two of the Cloyes units this season. In their defense, they were used or ran for multiple seasons, but for what ever reason, both were toast this year. One in each car....one was super loose, the other stiffened up after removal and locked up.

Not sure what my engine build put back in....But open to suggestions as I will be watching it...

i got mine(progear) from mancini............they are the best out of any timming chain ive ever used and very reasonable

Milodon gear drive and be done with it. Your valve timing will be the same a decade from now.

And before we get any further down the road, I would love to see any VERIFIED testing where gear drives cause harmonics. I have never seen it. The only testing I could find on the web was done by a nascar team and they tested a belt drive against a chain and a 4 gear drive. The 4 gear drive may be worse than a chain.

As someone else said...........chain links don't stretch. Pins and gears wear.

Was this directed to the OP, or to my reply prior to yours?

Don't want to speak for Monte but I think he was clarifying that the side plates don't stretch or wear. So the chains don't actually stretch. The pins wear out.
