Timing Chain Choice

IMO, the ONLY choice is a Cloyes TRUE roller, part # 9-3103. Not a double roller. The double roller is their cheap line. The True Roller has the beefiest chain (made by Renold - it will be stamped on the side bar of the links). The rollers are hardened and really roll. Many of the cheaper chains don't actually roll, they slide on the sprocket. Go to your local parts house and ask to see both. Compare them side-by-side. I've built dozens and dozens of engines with this model and never had a problem.

As far as the Rollmaster chain is concerned - I used one once. The billet sprocket is nice, but the chain is junk. It's made by Olon. I beleive it's Japanese. They wear out quick. Plus, it was loose when I put it on even though we bought an .005" shorter set to comensate for the line honed block. I wanted to replace it, but the guy who I was building the motor for was in a hurry.

Don't skimp on the timing chain. Your car will run better with a high quality chain due to less spark scatter.
