351 2V ---> 4V in Engine, Transmission, Drive Line, Etc Posted January 23, 2017 Not to muddy up the water, but it you were to look up on Power Nation dot com. The TV show is horsepower. you should be able to lookup the 351 Cleveland 2v versus 4v rebuilds they did with junkyard engines a couple of years ago. They actually generated more horsepower with a 2v than with a 4v. something to look into before you dump all that cash into a change so to speak. Just trying to help out a fellow member.
