anyone running wiseco junkyard dog pistons? im planning on running them and they say there "drop in replacement" now I know that forged pistons expand a lot differently then other types of pistons and they need more of a piston to wall clearance. do I need to take my 5.3 block to a machine shop and have them bore my cylinders a little over stock to run those pistons or no?

 

If you have to do all that, then they aren't exactly drop in are they?

 

true, idk just being cautious before I spend the money
