trying to decide wether to build my 340 or my 440. i have a 71 challenger that i want to drag race mostly (not an all out drag car, just a fast streetcar). my challenger is a facvtory 318 car, and if i build the 440, will i have to change the k-member? my mom has a 72 challenger and she said i could drop the 440 in it and drag race it and take my time building the 340 and put it in my car. just wondering what you all would suggest.
