Turn a small drill press into a Bore/ Hone. Bolt it to the top of your engine block & do your own machining .

Just buy some **** off eBay from the 40s and 50s, probably more accurate than using your drill press n blowing out your elbow n the block spinning round and taking out your kneecap. If it ran it'd make all kinds of piston noise n burn oil.
But hey...who am I to tell you no, right.
So do it. what's a block anyways. Lol
Just get custom pistons for every hole if ya have to, make the dream a reality

:thumbsup: lol
