Help me pick out pistons for a 346.
My buddy wants to swap the pistons and rod bolts on his 2001 SS. It has about 60,000 miles on it, and doesn't want to put valve reliefs in the stock pistons. He is considering the JE pistons. I looked at some sponsors websites who have them, and I didn't find them in a 3.900 bore. Most start at 3.905. Anyone know were one could find them for the stock bore size? thanks

You simply do not remove and change pistons without honing the block.
How can anyone miss this issue
Tell your friend he either rebuilds the block or he flycuts.

you hone it so when you put the new piston rings in there(which I hope hes doing) they break in their own wear pattern. Otherwise, you could end up with some leaky piston rings and blow oil everywhere. Youve heard this plenty of times, "If your gonna do it, do it right."
BTW...even on old school motors, you should hone the cylinder before putting new pistons and rings in. That goes for just about every motor out there.
