Hey, I am looking for some suggestions on 69 dart project. The car now has a 318 auto 3 speed 2 barrel. The motor is coming out and I am undecided on what to put in. I have always liked the 340. With stock 10 plus compression pistons, a wild cam and maybe 360 ported heads and some other stuff my goal would be to get as close to 450 hp. People are trying to talk me into bigger cubes like 440, for the torque. Budget is limited and car is for Sunday drives not racing. A built 340 would be any easy swap out from the existing 318. All suggestions most appreciated.
