And a Performer intake is pretty much the same as the DP4B, but will accept a Thermoquad or other spreadbore carb. Worth considering in my opinion.
The 383 is already torque challenged down low. Don't put a single plane on it
A mechanical cam is the only cam I'd put in a 383 application if you want to mazimize street friendly power. Unless you really don't care about power and performance, and only low end torque put some tiny cam in it and go ahead and keep it hydraulic.
A Performer is a good candidate. I will look around.
For sure, I will go for a dual plane. With a single plane I won't even get near my goals.
Explicate why a mechanical cam would perform better in the lower rpm range. I have honestly never digged into that field. I have used mech cams in high revving street/strip engines but not in something like this.
