Thank you for bringing that point up about the adapter. Which is the best way to go? Reason I ask is that I have my original balancer and my flex plate. If I order a kit that has a 2 pc crank, I won't need to buy a new balancer or flex plate I assume, where as if I buy a 1 pc crank, I guess the bolt pattern on the crank is different. Very good point. Does Jegs or summit sell the adapter? Will I be able to use my oil pan as well. I would think so.
