I just received my January 2014 Popular Hot Rodding in the mail today and found an interesting article on Hinkle Performance (London, KY) build of what they're calling "Mopar's throwaway big-block" 361.
You're going to have to read the article for all of the details, but using some creative machining of the stock forged crank and innovative thinking, they ended up with a 412" engine that dyno'd at 618 HP @ 7000 rpm and 520 ft-lbs. of torque at 5100 rpm. This is a pump-gas friendly 10.4:1 that pumps out 420 ft-lbs. of torque at 2500 rpm and climbs from there.
Good read!
