I've had some really good news from my latest (third) engine builder. History is that I had a bad vibration from my 428.
As I suspected (or at least one of my suspicions) the engine, when originally built 15+ years ago, had been internally balanced and I bolted a weighted 428 flex plate to it unaware of the internal balancing.
The bad news is that there was a lot of shrapnel from the wiped lobes still in the engine despite it been stripped down for the new cam by the last builder. All I plan to do is to take of the weights the from the flex plate and re install.
