What is the preferred Cloyes timing chain set for a 455? In looking at the Cloyes website and Summit Racing it appears that there are two choices:
9-1113 "Street True Roller" (approx $70)
9-3113 "Original True Roller" (approx $110)

I have the original true roller in mine. When I rebuilt my engine with 50,000 miles on it the chain had very little play in it. I would spend the extra few bucks for piece of mind.

Steve,
If it's the same deal as on the Cadillac, the gears are the same.
The difference is the chain. The cheaper chain is Chinese.
That said, the Caddy guys say it works fine. YMMV

From a post on the Corvette forum:
Depending on the terms being used a true roller generally means that there is a pin connecting the links of the chain and a roller that goes over the pin thus rolling as the chain runs over the sprocket. A 'street' roller just has the pins. The overall dimensions of either are the same and that is .25" diameter pins or rollers. When you get a true roller be certain that it isn't a split roller, meaning the rollers are made with a seam in them. These types are prone to failure under extreme conditions because the seam is the weak point. Get a true roller with seamless rollers if you want the best quality. They, of course, are much more expensive than a normal 'street' or split roller chain.
Oh, one more point....true rollers are sometimes called double rollers but don't confuse them with double row chains. You can have a double row, double roller chain (most are) that is also a double row true roller chain. As always people misapply the terms and call double row chains a double roller. So have a close look at what you buy or a general rule is if it costs around $90 US or more then it is probably a true roller. When you look at the chain use a point of a pen to try to spin a roller. It it's a solid pin then it is a 'street' type roller but if there is a sleeve that rotates then it is a double or true roller. As an example jeg's/cloyes p/n 220-9-3145 is a true roller with rotating pins/rollers but p/n 220-9-1100 is a 'street' roller with solid pins/rollers.
Also found this:
Street TrueRoller has three keyways on the crank sprocket - one for stock (factory) timing, one for +4 degrees, one for -4 degrees. Also I think the cam sprocket is either cast iron or a harder steel alloy than the $45 TrueRoller

Mike,
From the descriptions below I don't believe the last sentence is 100% correct. It contradicts with the previous sentence and this

The pins do not rotate, only the rollers do.

Thanks for finding that quote. It appears the 3100 series is the one I am looking for. Now I just have to pull the front off the engine and see what is in there. (If I order it now you can guess what I will find in there.) I'll do a cam chain test first but no matter what the result I will have a look to make sure.

Steve,
Of course it's the 3100 series, it's MORE EXPENSIVE!

I'm just thankful that my GMC is not a boat, or an airplane.
