Heh guys im curious as to if the beams 3sge pistons can pe used in older 3sges like gen 2 and gen 3 engines, are the pistons the same design except for compression?, is pin size the same?, what about the valve angle of old heads and beams head? Can i just use beams pistons as a straight swap? Thanks for info guys, also are rods in beams lighter or the same?
