I’ve read a bunch of what you’ve written on balancers and have done probably 1/8th of the research. I don’t disagree with what you’re saying at all. If I was building a road racing car with a powerband of 2000-9000 I’d make a different choice than I do for a street car or my boat. The twin turbo big block runs at either idle or 5900 with how I have it impellered and Tom was certain the ATI would handle it. And it makes big time power. Street car stuff 1000-6000rpm you can throw just about anything on under 600hp and be just fine.
