Size is HOLE SIZE, not piston size, pistons will be slightly under those sizes. We strongly recommend buying the piston, then honing your cylinder to your piston, as piston exact sizes can move by a vary slight amount.

Our HP Tillotson Block Kits currently start at 2.987", giving you another piston size for freshening in the future.
