I am in the same position as you. looking for a 90.5 stroker piston. I have 4 barrels and 3 pistons! the forth one is a little mashed as something metallic fell in ther cyl. as they are mahle so would rather not bin them .strongy said:is there anywhere that sells them single rather than as a set? only need 2 pistons and 1 barrel but looks like ive got to splash out on the full set?
