Not sure, but you should have received info on piston to wall clearance from the piston manufacturer?

That's pretty excessive to me, I'd like to see more like .0035-.004". That much clearance might cause some piston slap when the engine is cold.

I know its a bit excessive problem is its the way I received it only question now is to start over or run it. Im ok with a little cold piston rattle but I would prefer not to have a diesel.

Personally, I wouldn't accept that for a street car. I'd fix it or run a different shortblock altogether. I don't think it will make a horrible amount of racket, but then again, it could. What I can tell you is that it won't cause it to blow up or anything.

anyway you can return the pistons and get the correct ones? If not I would sell those and go with a better fitting piston...I would rather do it right the first time and lose a little money then do it multiple times
