Check these pistons out. Good prices for a 2618 forged piston. I have a set from when they were sold under the Keith Black name in my motor now. Very nice piston for the price. I got lucky and ordered mine from Summit not knowing that they had the wrong price in only for the piston I needed at the time. Paid 275.00 for set of 8. Had I looked at any other sizes on the sight at the time I would have seen I saved a couple hundred dollars and I might have ordered a couple more sets.
