I wonder about 5.3 block bored to 346 cui. Like I know the machine shop usually bored 0.30, 0.40, 0.60 But our blocks are a little different than old time school model from others. If I ask person to bored. Just say 3.898 correct? And get piston same size 3.898 to make 346 correct? Let me know please.

Each piston will require a different piston to wall clearance. The machine shop would need to know the size of the pistons. It is best they have them in their hands and the piston manufacture recommendation. Wouldn't hurt to know what you are planing to do with it. If you read a few post up, you will find that if you plan of boost or n2o, bigger may be better....

beastmode - man you will be fine dont worry about it. i doubt it'll rattle any, but it will use some oil which still isnt going to hurt anything except for tuning maybe
go5.3tt06 - the 4.8/5.3 block will bore to a stock LS1 bore without any problems and support lots of HP
