OK, I'm cheating here because I know the answer. Even so, I'd like to sort of gather some opinions in order to help me formulate an article I'm about to write.
Here's the deal: We built a 383 at 0.060 over, stock bottom end, Diamond custom pistons for 10.3:1 compression, bone stock 906 heads, and a custom Comp MM solid flat cam that's like 237/242 at 0.050 on a 110. I'll tell you that the engine makes in the range of 450 lb-ft and 450 hp all under 6,000 rpm.
We tested 15 intake manifolds, altering jets on each one for optimum power. Here are the intakes we ran. The carb was an 830-cfm Holley except for the Offy 4500 intake that used a King Demon, the Six Pack that used 440 Six Pack carbs, and the dual-quad that used Edelbrock 500s:
Edelbrock DP4B Edelbrock Performer Edelbrock Performer RPM Edelbrock Torker Edelbrock TM6 Edelbrock Victor Edelbrock Six Pack Weiand Team G single-plane Weiand Action Plus dual plane Weiand single-quad tunnel ram Offy Dual-Port Offy 360 for 4500 carb Offy low-rise dual quad Mopar Performance M1 single-plane Holley Street Dominator
Which intake "won"? Which one sucked the most? Which one do YOU run?

single 4 bbl t ram? low rise dual quads? no offence but after reading your last dyno session with a t-ram and not tuning it correctly ( right carbs ) i thought you would have at least gave it another go and tried.. i bet a dual quad t-ram would have beat or held its own against the competition...provided ya did your homework this time...

I'd choose the RPM as well with that combo, but I'm more than a little curious to see how the 6 pack setup did, which no one has mentioned as yet to the good or to the bad.

Define "won"
Well, I sort of left it open to interpretation, which is why it's in quotes. Take your pick: best peak torque, best peak hp, or best average lb-ft or hp. Name it.
