Much lighter piston than any ive seen

The Wiesco piston i was running was probaly twice as heavy.
I bought a blockzilla 2 and found it had a cracked piston from not being clearanced enough and was hitting the head.so i orderesd a new one put it in and thought its the same size as the clone. so i pulled it out and put it in the clone and found it made more power and better pickup.
