No 7 piston is shot. There is damage to the head as well. I believe that the spark plug broke and had been sitting in there and they just kept driving it. I want to use the 862 heads that I have on my 5.3, but need new pistons and it will get new main bearings and a new cam. What do you recomend on pistons, new ones, one or two from a junk yard????????? Btw the motor came out of an 05 van. They told me it smoked, thats why they pulled it out. I will get some pics of the damaged piston and head and should have them up later. I do want to spray when at the track but will not be doing it all the time.
