[STATUTORY GRAPE]

For my '72 Duster I was planning on putting in a '74 360/4bbl. but found a '72 Dart with a 318/2bbl. My Duster was originally a S-6 but would it be worth more money with the numbers matching (or at least year matching) 318 from the Dart (with all #'s matching accessories + tranny) or the '74 360 which came from a truck? The 318 would be so easy to swap since all the underhood accessories are already on it and I pulled it with the tranny still attached. I was planning on leaving the 7 1/4 rear end in the car and just driving like my Grandma until I can find a bigger rear end. The Dart that the 318 came from has a 7 1/4 also so it must have held up with the 318 power for all these years. How much H.P. can I expect to have from the 318 2bbl.? I'm guessing around 180-190. That should be plenty of power for a car that light, huh. I just plan on doing normal driving, I don't abuse my vehicles. Would the 318 qualify as a "#'s matching" motor even though mine had the S-6? With all due respect,, I would like to have ALL of these questions answered if possible :thumbup: :welcome:

You do know that you have to change the "K" member to put that v8 in place of the 6, dont you?

No, I'm planning on just getting some "Schumacher conversion motor mounts" to fit the S-6 K-member. I don't know for sure on the weight difference but the 318 can't be THAT much more than a S-6 :nono: . The torsion bars, springs, steering components, etc.... are all exactly the same from the 318 car to my S-6 car. Even the steering bar (can't remember what it's called) that goes under the oil pan on the 318 car has the exact same drop as my S-6 car. The two pitman arms and steering gear box are indentical also :thumbup:
