The newer -0411 or "silver" ECM is a popular upgrade and is a faster and "smarter" ECM, able to control any powertrain combination and dual electric fans. The upgrades that I have been looking at is a cam, long tube headers, and a tune. upgrades to a 240z. Back when I was playing with them the headers (or even the better elbow) and the heads were key. 1 speakers from dynaudio. In addition, the 383 cubic-inch engine sported a 750 cfm Speed Demon.
