I have a 68' Barracuda fastback with a 318. I need to do a transplant and I don't know much about Mopar engines as far as to know which engine would give me the best h.p. and torque. Fitment is also a small issue. This is a street car, but I don't mind strip style power. Any info would be helpful. I will cross the tranny and rear end issue later. The car is drivable now so I have time to do my build. If a 340 builds better and runs better than a 360 or visa versa is what I am trying to find out. Thanks guys.
