I'm in the process of building a 331 stroker (it is balanced 28oz). I purchased a FRPP 28oz balancer from Summit that says it will fit our cars. First, it was slightly larger in diameter so I had to grind some of the bottom water pump mount bolt to get it on. No biggy. Now it sits in to far for the crank pulley to line up with the rest of the pulleys. I looked at the stock one and it has a 11/16" cast raised center for the crank pulley to attach to. Does anybody make a spacer or a 28oz balancer that will work?? Any suggestions?? This is the only thing holding it up from going back into the car.
