Curious on what sleeves and piston need to be used after matching the block on a 426 to make it 466 cubic inches?

Easiest would be custom sleeves and pistons. Will hold up better than cast iron sleeves and stock pistons because of better material.

You will not need to bore the block to get 466ci just a 4.450 bore and find a piston close to that or custom piston

We use cummins pistons with allis rods reworked to fit and a custom sleeve. Puts it a bit past 470ci
