Whats everyone's thoughts on B/500

I like the shorter rod combo for the B wedge 4.25" strokes. Aftermarket rods are easy to come by, chevy crank pin and .990 piston pins, and a little taller compression height so no oil ring support needed. They make great street engines and will last fairly well (20-30K so far, with some racing and highway blasting). You will need some real heads and a camshaft to feed them at the 800hp level. That aint "RPMs" and a hydraulic flat tappet" deal.
