The pistons he has now are fine, and he has no plans of nitrous or boost, so stock parts will suffice.

What are the cheapest 4.030" pistons just in case the block has to be bored?

When I bought new standard pistons for my 350, the .030 were the same price. Just have to look

so a grand later he has a bottom end...

Or pick up a good block for under 300 and have it honed tanked and inspected for around 250 bucks.
