"Hi, i'm building my 347 stroker with a V1 Vortech Sprchrgr. My questions is, which brand 28oz harmonic balancer would you recommend? The car is for street strip." Damn, I apologize for the delay. I didn't see, nor look for new notifications on my profile... sorry for that. If you haven't bought your damper yet, I really like to use BHJ then ATI. Most of my stuff has been neutral balanced, but recently I built a 28oz 347ci sbf with the BHJ.
