Help!?! Just took apart my 360, and found bad things!

Are these "Sealed Power" pistons any good? $400.00 for this set seems fair, and just may be the way to go? Are these equal to stock or a bit better?


I'm running the cheapo Summit rebuild kit with those pistons in a 40 over 360. It was in a 73 scamp as my daily driver with no problems. Now the motor has a duel tunnel ram and is going in my 53 Merc pick up and that will be a daily driver.
