maybe.....although can't imagine it being
that bad.....
always ran premium in the tank, with Chevron fuel injector cleaner once a month. Never heard a knock or rattle out of it....
#8 developed issues about a month after I brought the car home, but I was sure surprised to see the rest of the damage....
Funny thing is, some of the pistons that had a broken ringland did not have a broken top compression ring---it was very random.
Last one I had broke up like this was a 426 wedge MOPAR with factory cast pistons and the heads shaved so close I had to notch the pistons .150"......Darn thing broke ringlands right and left, seemed like a changed pistons twice a month when I was racing it.
