Hi There, I am currently building up a cast iron LS2 which i will be using a double row timing chain, and am planning to use a Innovators West Balancer. Can anyone tell me if i would need to machine the balanacer to compensate for the timing chain or how would i know if i need to do this. I haven't bought the balancer yet but am just planning ahead before i take the plunge and buy one.
Thanks in advance.
