Mopar purple .528 for a 383?

Just wanted to chime in regarding your carb choice, a Street Demon might not work too well with that cam especially on a single-plane intake. If you already have the carb it's worth a shot but if not I'd suggest something better suited to hotter engines with low idle vacuum (Holley DP??) as that's what I assume a 383 with a .528 Purple Shaft will behave like. I'm running a 750 cfm Street Demon on the 360 SB in my Duster with ported Edelbrock heads, 9:1 comp, RPM non-Air Gap intake and custom-grind .548" lift cam with 274/278 adv. duration, 222/226 @ .050 and it's kinda borderline in terms of tunability and fuel delivery for the combo.
I was only going to try it for testing purposes to see how the two manifolds stack up. But the whole build just took a 180 as I found a screaming deal on a set of aluminum heads.

So I will be selling(this is not an ad Mike)the street demon, dp4b and 906’s and putting that money towards a carburetor. I’m not sure what carb I’m going with yet…. the ever evolving build.

Now the cam will be the limitation, but I have to stop the madness so I can actually drive this thing one day. I’m committed to the .528 at this point. My whole build is centered around all the cool **** that makes Mopar awesome. So the old school mopar cam fits the build, and should sound wicked with the Hedman long tubes and Dynomax ultra flos.
