On ebay there is a Dart "Big M" kit for a 598cid BBC #59865DBK for $3,700 which includes 1 Big M sportsman block, cam bearings, rod bearings, main bearings, freeze plugs, forged crankshaft, H beam connecting rods, forged pistons & plasma moly piston rings. Included with this auction is free shipping to any business with a loading dock. I am considering this, but I have no idea if this kit is way cheap or what? Perhaps Eric or Pat might provide some insight?
