Re: 406 vets needed
I ran a 383 (same stroke, slightly lighter piston) in my truck with a ductile iron crank and external balancing. Motor was street driven and raced considerably for 5+ years or so. Shifted at 6200 (because of a hydraulic roller cam or it would have been higher)
It beats up the bearings at higher rpm's more quickly than internal balancing does is what I've found. I have to agree, if it's a serious track toy then do it right the first time and build with forged crank, internally balanced, neutral damper and flexplate. But I've built a number of upper end street motors that were externally balanced and survived the occasional trip to the track just fine with even 6500rpm shifts. Nothing I would prefer to make a habit of, but it will survive. IMO

I just did my taxes and reviewed my SS statement. Thanks to the current administration it looks like I will only have to work till noon on the day of my funeral.
