So, just basically a Hoover motor? Tom Hoover did it in the mid '70s, he basically used a 360 crank with cut down mains, and heavily re-machined '73 340 low compression cast pistons (crank clearancing the skirts, shave a bunch off the tops). Pop Rod did a writeup on it, as well as other sources- Google "Hoover 360" or "Hoover's Mover". Went like stink (Of course it did- this was Tom Hoover, man) at a time before strokers were common and there were no 360 pistons available.
