From the combination described above: Edelbrock Performer RPM....#1 Edelbrock Six Pack..........#2 (maybe even #1...) Holley Street Dominator....#3
My experience w/ the old Torker intake on a mild 383 combination many years ago was pretty surprising, too. Even though it was a single-plane, it still ran waaay better than the OEM cast-iron dual-plane intake it replaced. I'll be curious how well it compared.
