school me on stroker smallblocks

A professional balance job will come with a sheet showing starting and ending balance in grams and the progression to get there. I wish I had a scanner. It's amazing how far a factory stroke, KB pistons, Eagle I-beams, aftermarket harmonic damper and B&M flexplate was off balance. Never trust a kit manufacturer to have the balance right on the money. This is even more critical on engines with a longer stroke.
