I used a Livernois Stroker Rotating Assemby in my Mach I. I think it cost $2,300.00 at the time; no trouble to report.
I had the cheap Coast High kit in mine seven or eight years ago. At that time they used a no-name Chinese crank (which, BTW, all cast SBF cranks come from China) that had tapered rod journals and the mains were tight. Now they use Scat and RPM cast cranks (both also Chinese but better quality control) and are much better. They all need to be checked but Scats often don't need any dimensional "adjusting".
