Edelbrck vs Trick Flow

Hard to say about the difference. As they say, 'it is all in the combo'.
The E heads might have had just enough port volume & flow to work well with the cam & intake & you get a very efficient combo. The TF heads may have had larger ports that flowed more than was needed for the rest of the combo, made a little more hp, but lost tq through the rpm range...& et suffered. Just using this as an example.
A good example I know of [ not a Mopar ] but illustrates the point: 4000 +lb Pontiac LeMans waggon, 455 with factory heads ported by the owner, AC, 3.55 axle. Crane HFT cam 234/242 @ 050. Full exh, T400 trans, full size c'ter with some stall. Edel RPM int, QJ carb. Has run low 11s @ 117 mph. Jim just chipped away at it until everything worked together.
