The engine in my C8 has the original cast iron pistons in situ, these pistons have been known to break if stressed too much, the piston top comes off
I purchased a set of aftermarket Aluminium based 216 pistons ( when the postage from USA was cheap) , but surprise , they weigh only 25% less than the cast iron type .
