79 440 in a 67 dart?

Honestly, a 79' 440 is a big smog motor, low compression no power (earlier 440's had forged goodies too). That 273 ya got probably isn't too much less power than the 440 (although the torque would be higher). It's alot of work in the front end meaning suspension upgrades, different motor mounts, expensive headers etc...This is the thread i posted because i have a "similar" predicament so maybe read through and see what some guys said, i'm still on the fence haha
