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

Only mod is, I already bought 9:1 cr pistons/ standard size with rings...cheap enough..hope I will get more miles out of the old engine, this one going in a short bed , stepside 82 D150 p/u...gonna use the stock 4 bbl TheroQuad and intake...building it, pretty much for gas milege. Won't ever see the high side of 5500 rpm.
