67/68/69 cuda dilemma

Also looking for a decent street car balancer. The rotating assembly has been balanced. So that's good. I have been checking out different balancers on rockauto. Any ideas. I have a fluid damper for my stroker, but want something a bit cheaper for this.
dorman makes a good unit that's fit for street use. i've also had good luck with professional products piece that's neutral balance but comes with weights for the other motors.
