Im comparing the rat pin that im using in the ross pistons designed to use a rat pin, 151 grams, with the stock, or trw pin used in a stock 440. My point is, if you use stock length mopar stuff, a LOT of weight can be saved if the pistons are designed for the shorter, lighter pin. Exact same bore size.
You want light? Put in small block chevy pins. My tool steel pins in my small block are 85 grams.
