Interesting thread, cause I haven't heard of anyone doing engine PnP & blueprinting nowadays. These used to be so popular during the days of illegal drag races when single or double side draft Solex & Weber carbs were in vogue. Engines were simpler then. My friends just used to use a rotary brass bristle brush & a flex shaft connected to a hand drill. Blue printing then then was just changing to race camshafts, a PnP & Solex or Weber double side draft. Along with a change of suspension, your good to go. Nowadays, di na pwede into, but it was fun then.
