My very first mopar

fisrt you need lots of money. id build the 318. the 440 will suck gas and make power. but with this crappy econemy you need to think it thru a little better before dumping all the money you make into it. i have a 300hp 318 in my Dart Sport and itll do just fine. you gotta remember how light these cars are and there is honestly no weight in the rear so you dont need all that motor. if you do a 440 you have to beef up the frame get a new rear get 500 dollar headers and 100 dollar mounts. 318 you can rebuild and make gobbs of power for under 2000 bucks and have to make no bodily changes or drivetrain swaps.
