The 5.9 is out of car at the moment. No parts have been ordered so far. My build for the 440 alone is somewhere around the $10k to $12k mark. I have a 23 spline 4 speed. Ive been told that wont hold what i'm trying to build and neither will the rear end. Assuming they can survive, at the very least i need a new bell housing, motor mounts, and headers. Probably a radiator/ oil cooler. Building the 440 will break the bank something fierce. Money is not my chief concern but i could build the 5.9 and buy another Mopar. I love the car so much as it is. I may leave the 440 for another Mopar, probably a B-body. So to say the least, im very indecisive at this point.
