Zippy...I don't now what heads you'll be running or how much cam you're gonna use, but the Barton/MP 4150 intake will be stronger than the Indy 426-2.
I'd think the 426-3D would rank below the Barton, but be somewhat similar to the 426-2.
I should have taken some pics the other day, but I will later this week...I have my hemi out and apart. I have the Barton 4500 manifold on the table next to the big Indy 426-4.
