383 procharger

[DeltaT]

I have the raised port (+.200") Edelbrock E-Tec 200 Vortech-style heads, and I had to fill in the holes in the headers and redrill them .200" lower to make the header match the port opening. Every one including Hedman said they'll fit, and they WILL bolt up correctly, but they would have badly shrouded the top of the exhaust port where the flow is the strongest.

I'm running a Vortech-blown 383 as well, and it put down a first dyno of 501rwhp a couple months ago with only 7.2# of boost.

Solid roller cam 230/236 with net lift of .575"/.584" on a 112LSA makes a great street blower cam.
