Also, I see that Cloyes makes one as well. Is there a difference in quality between the Cloyes one and the factory one? Does anybody know the part number for the factory piece?
When I put my engine together a few months ago the factory one was not available... dont remember if it was on back order or dis continued... I got the Cloyes

Your dealer or auto parts store can get you one. P5007709...same as used on Jeeps...5.2 and 5.9 trucks, and I think the 3.9L. Keep in mind, timing will only bounce in a case like this at slower or on and off speeds. A timing chain will always have tension against ONE SIDE while under power. Or at least it better. You'll always have a tight side, and one more slack. If its a horrible fitting chain right fromt he beginning, then this could serve as a bandaid. Its funny, you dont see SBC having to run them. Hell, they still successfully use a single roller chain on the late model cams with great success. As you can see, we dont all agree.... ...its your vehicle, do what makes you comfortable.

SBC doesnt have the long cam to crank centerline a SBM does either--which is why these engine are hard on timing chains to start with. That said I dont run one...

When I ordered my Rollmaster chain, they asked me if I had linehoned the block, I said yes, they asked how much, and made it 3thou shorter, and it fits nice, not to tight, and not to loos, there is zero play in the chain, and I have a lock collar on my distributor shaft to keep my cam gear from bouncing. My timing is ROCK solid. Kasey

When you see how much the nylon wears in such a short time, and it's all in the oil/oil pan you'll never run one again!! Gimmick if you ask me. Buy a good timing set and be done.
And I agree !! 100%. it is a bandage for junk timing chain set,,

This is about SMALL blocks,,,big blocks don't need tensioners/etc..they will still run good with 'sloppy' chains,,,right, Vern.??

This is clearly one of those "builders choice" items. I've built them both ways and can't really tell any difference in how they ran. Two things worth considering. One: these tensioners were intended to be used with stock type link chains which have a much smoother back than the double rollers typically used in performance builds. 2nd. If you do decide to use one it may not be a bad idea to drill the 4th. bolt hole in the tensioner [ use a standard cam retainer for a template ] and use a bolt with an 1/8 in. hole drilled through the center in the upper left [ looking at it from the front ] bolt hole. This bolt goes through the front of the block and sits in a pocket in the cam valley that collects oil. This would allow oil to drip directly onto the chain and possibly improve wear.
