I like the thought process on this. The rods that are going in my .030 340 for now are aluminum and are alittle shorter then the stock 6.123 rod length because of rod
stretch. To even make things better I'll be running a trw .030 12:1 piston. Next motor when I have more then enough money I would love to experiment with stuff like you had mentioned. Also with lighter pistons and crank. A lite weight stroker rotating assembly would be interesting!
