so alot has happened in last few months.
bought another 5.3 for 250 bucks that was promised ran when pulled but stored out side. found rust in cylinders. bad in 7. decided to stop messing around so sent it out to be reworked.
this is a lie
tanked,bored, linehoned, and new cam bearings
the secret is these are not 5,3 pistons. they are 5.7
they are going here
