You may need to define "best".

Best performance at low rpm/high rpm?
Street/Track?
Fuel consumption?
Airflow numbers?

You should probably state what usage you are looking for in regards to operating the vehicle.

Air-gap,my 2 cents-------------

gingerbreadman1977

between the 2 of them there is very little performance difference. nothing you would notice anyway but i have to admit ...an air gap looks BLOODY GOOD !!!

Street... low rpm...

Do they [edelbrock rpm ] make one for the spreadbore? I have had pretty good luck with the wieand 8004 for street low rpm. If they are squarebore you will need an adapter for the rpm manifold.

Edelbrock Rpm have one with spreadbore .

what heads you putting them on???
what rpm range is your cam??

if i remember right, the RPMs are good for an extra 500-1000. from my research, your heads better flow like a jet engine to need the rpm

Will the air gap fit under your hood?

They both have the same deck height.

I have the Air Gap on my 79 with stock hood. Love it!

Both the rpm and the air gap require a drop base air cleaner to fit under the hood, so if you have a stock dual snorkle cold air intake system, you loose more performance than you gain. Also, the rpm air gap will not work with a Quardajet, so there you have two strikes against it. If you are looking for normal (low rpm) street driving, the regular Performer is your best bet; fits under the hood with stock breather and carb. God bless, Sensei
