Speedmaster vs Edelbrock air gap intakes

i went 1.34 on that stuff. Its not hard to get a car to 60 foot respectably without much money. Especally A body Mopars with good rear overhang.
Heck my old Duster with that 318 enginemasters mill ran high 1.50’s on stock leafs and New Yorker shocks.
4 speed..?..
