Speedmaster vs Edelbrock air gap intakes

abdywgn said
the Professional Product air gap made 477hp on a 318 in Engine Masters some years ago.

i ran that engine in a 71 duster i had. Intake looked good to me. I seriously doubt it loses much if any power to the eddie intake, with both cleaned up, matched to heads.
It pulled good to 6500, although i shifted it slightly lower
