349 CI on the cheap

Well 40 over out of the question I wonder if I can find an off the shelf 70 over piston By my reckoning that would allow a "357" badge add a set of Magnum heads and call me "Dirty Hairy-this is the most powerful 318 on the planet so you gotta ask yourself ,Do ya fell lucky ? well punk do ya ? " hahaha . good luck at the track eh
