Does "interesting" include having a big basket handy to pick up the pieces when you scatter it all over the landscape? Hotrodding a 401 V6 makes about as much sense as painting racing stripes on a snail! Those engines are torque monsters, with factory-matched and balanced crankshafts and piston assemblies. Just swapping crankshafts was usually very risky, according to the machine shop where I worked that sort of specialized in keeping the big V6's running 30-something years ago for some of their oldtime customers who still had trucks equipped with them.
