timing chain info needed 98 ls1 semi built
saying the jwis chain maybe if will work with torrington bearing wored into the combo. like i stated this is my girst at timing chain on ls1 and wanna make sure it right and can correctly be adjusted easy. i want a single chain and upgrade cam gears. got anymore infor for me 405hp? thanks
The JWIS chain I have is from Katech. Note also that IWIS Ketten makes several chains in this pitch and size so you have to be specific on which one. The Katech chain does not have a seamless roller.
As for N-motion, we had another thread on this. N-motion is made for SDPC by JP Performance and it re-branded (hope that's the correct term).
I spoke to Cloyes, they did confirm their upper cam sprocket could be machined for a Torrington, not sure how much that would cost though especially on top of an already expensive timing set.
Not sure which IWIS chain Rollmaster uses, they may have seamless rollers. I also corresponded with Ed Curtis of FTI and he pulled a couple of Ford Rollmasters off the shelf and looked at them. Both had seamless rollers, one was an IWIS Ketten (JWIS) and the other was a Rolon.
Confusion reigns supreme.

Then throw in the normal manufacturing delays and supply problems assocated with parts sourcing and it's really a crap shoot what you'll actually get in the box.
The Torrington bearing sits between the cam gear and the cam retainer plate. Normally, the cam gear spins against the plate and uses oil to prevent wear. However, there are some oiling issues in this area (Vinci has some good photo's>>>>) and with the Torrington bearing, the cam gear no longer will rub against the cam plate, rather the bearing sits against the plate and there is no wear.
If you look at the chain, where it fits into the sprocket is the roller. The roller sits on a pin that goes through the center of it. On some chains, the roller is one piece like a pipe. On others, they are formed from flat stock and basically bent round which leaves a seam where the two ends join but it is truly not a tube. If you think of something like a carboard roll in the center of paper towels. Seamless would be the roll you get with no paper towels on it. If you then slit it along the entire length, it would still be round but there would a slit (seam) in it.

I PM'd someone in the business about some questions I had on my JP Performance setup and he told me that they had recently bought out Rollmaster. I haven't seen it anywhere (like a paper) but since he is pretty close to many of the company owners in this business I think his information is probably correct.
Your correct, this is what I just got from Rollmaster/Romac:
"Two months ago the business of Rollmaster Timing Gear Sets and Romac Harmonic Balances were bought by Nornda Automotive which is part of JP Performance."

Verdad Gallardo What's interesting is I wonder how much they were cooperating before. The JP sprockets look very much like the Rollmaster and I wonder if they were making some of their parts for Rollmaster prior to the buyout.

I just (10 minutes ago) purchased a COMP Part #: 3153kt Billet Steel Adjustable TC off of Ebay. It has is 9 keyway adjustable for 8 degrees advance or retard and has a Torrington Thrust Bearing. Price was $102 shipped. We'll see how it works.
It is advertised as fitting behind stock covers too.
