I bought a old Bryant top fuel full counter weighted 4.250 stroke years ago, it had spun the #1 and 2 rod bearings on the original Mopar size rod journals.
I had it magged and then offset ground to 4.375 stroke with 2.200 rod journals, I'm going to use it in my Koleno high nickel iron block to make a 555 C.I. race motor with a set of B1-MC heads, I'm hoping to make right at or above 2.0 HP per C.I.
Gregs Dart convinced me about using full counter weight stroker cranks several years ago so I'm hoping for good results
I wish I had enough extra money for a fully light weight version of that same crank, but I don't
