Deciding on replacement intake (318, details in post)

Current engine/drivetrain in my valiant is as follows:

318
167 KB pistons
360 heads ported
Lopey Isky cam (exact spec unknown but it seems there’s only 2)
Solid lifters
273 rockers
HEI distributor
Tunnel ram w/dual 450 carbs
Long tube headers
4 speed
3.91 explorer rear w/locker

There may be other mods as well but these are not known to me, no idea on output but it runs healthily and pushes the car along very nicely.


It may seem mad to some but my intention is to remove the tunnel ram & 450s and replace with something I can either get under the hood or a low hood scoop.

Reading on intake choice has pickled my newbie brain - air gap, RPM, or an altogether different choice? Car is not a daily driver, weekend/sunny day fun and the odd trip down the strip.

Advice is always appreciated.
