I owned one (a 1972 Plymouth Duster, Gold) many years ago (was my second car, my first was the '71 Charger, which I still own.) The previous owner had mounted a (former) Police-Special 383 engine in it (the '72 Duster, that is.) He didn't use the correct Big-Block/A-Body K-Member. Instead, he "made" some motor-mounts to allow it to fit (it wasn't that fantastic a job.) Also, he never dealt with the "Header" issue, as he used CI exhaust Manifolds. When I bought the car, it came without the Police Special 383 engine. My plan was to install another Big-Block (383, 400 or 440,) so I subsequently bought a correct-for-the-swap Mopar-Performance K-Member. After a fair amount of time and effort, I ran out of money and spare-time, so the car just sat. Eventually, I sold it. At the time (before I sold it,) I had planned to use Fender-well Headers with pipes that exited through holes cut in the inner-fenders, near the firewall. Seems to me (due to the vehicle-similarity) that BigBlockDart.COM website would prove useful in forming your project. BigBlockDart.comHere is a "similar" project car, but I didn't see how he dealt with the exhaust issue: 73 Dart Big Block swap project car

I would degree the cam before you install it! that cam loves advance from straight up spec and hates retard form straight up spec. the straight up spec is 106 intake install (max lift or intake centerline) I would put it at 102 with that TQ and less than 10.5 to 1 compression.
Flow bastards are noisy I would go with Dynomax ultra flows and an X pipe!

According to BigBlockDart.com its very possible to use run of the mill 1 3/4" headers on a 383/400 in an A body. Not on a 440 but a 383/400.
Keep old mopars alive.
