I have to go with Mr. Fixit on this one.....All the motors I build for myself have forged pistons in them and if anyone asked me to build them one,I'd insist on forged pistons simply because they are better and last and I have seen too many other non-forged pistons in the bottom of
oil pans just to save a few bucks,not to mention the ruined blocks and other parts destroyed in the ensuing mess....
As stated, most Cobras see few miles but they are usaully hard miles...............
