1971 383 upgrades

When I bought my 70 Polara it was all stock with a 383 2bbl.First thing was dual exhaust off of the manifolds.I later ran hedman shorty headers with that setup.Hooker super competition headers fit well on the 440 I put in later as well.
I converted it to electronic ignition with the old mopar performance kit as well.
Then a 4 barrel swap and a 3.23 sure grip and later 3.55's.
If I had kept the 383 in it after that I would have gone with a small cam and some head work.It is easy to over cam a 383 so be conservative.
