440RB INDY DUEL PLANE OR RPM INTAKE HELP

For timing chains the Rollmaster is excellent.

The least expensive I would run is this Summit set. The cam gear is a little soft and requires a lot of clean up to remove the proud metal on the edges of the cam gear teeth.

Never found a Rollmaster with a roller thrust bearing. I like a roller thrust bearing with the roller cam so I use this Cloyes unit. Has all hardened teeth and no metal shards on the teeth to clean up.
