Cant be piston slap had brand:

Longstudded 200 block
Pistons
Oil pump
S/H crank out of 35k engine didnt need grinding.

I cant belive he dont change them, im not being funny by not saying who it is but alot of people on here use him and i know it would get back to him. And thats perhaps not a good idea while hes got my engine, if he sorts it then all well and good, if he doesnt i will make him a post all of his own
