I am looking for a set of used forged pistons for Super Cobra Jet heads. I would like them to be for a stock stroke crank, with a 6.605 rod. I am putting together a spare motor and have not had the machine work done on the block so 4.390 to 4.440 bore will work i will have my block bored. I dont realy care how many passes they have on them, or what kind they are, as long as the skirts are not scuffed up to bad. Let me know what you have. I am located in Ames Ia 50010.
