im a young gun mopar girl and even i can tell you that is just wrong......My daily driven car is a 72 dart with a cast crank 440 that i swapped in myself with a 4 speed .....there is nothing wrong with a v8 swap......my car was originally a 318 car so i went V8 to V8.....but mixing in junk is going to kill it ........just shoot it up first with an elephant gun before putting in the chebbie motor......have you considered a tuner motor from a Honda or Toyota ....they are good on gas. :finga:
