[Ecotec] Double row timing chain worth it?

[chargedvx6]

JP and Rollmaster are the same company with the same sprockets. The JP set comes with a black Rolon chain and the Rollmaster set comes with a silver JWIS chain. There have been case of the JP set failing on some more extreme builds. None for the rollmaster that I've heard of though.

Rollmaster FTW

Anyone had luck with the Crow Cams Single Chain unit ? Interesting that the Rollmaster catalogue doesn't even mention anything after the VT. VX-VY not even mentioned. L36-L67 labelled as supercharged is so very confusing. I assume this single chain unit allows the balancer to remain operational and will need a new tensioner ? I noticed the StreetmachineTV L67 rebuild a few years ago used this chain with a tensioner with cam upgrade plus chargeer.
