Thoughts on this combo

Performer RPM and Air Gap are the same intake except for the air gap having an air gap...lol

the air gap fits fine under my 71 Duster...73 Duster..

you want the best HP...buy a holley double pumper


My car is actually a '78 Magnum. I kinda wanted to keep it a sleeper and need a car I can get in and fit my 6'3" body comfortably.

I want to get it right the first time since I have a lower back and neck fusion along with a brain tumor. I'm pretty close to being a cripple.


The Air Gap is taller isn't it? Someone stole my ported LD340 intake I had a few years ago. :banghead:

Street manners and economy are part of my goal, not just max horsepower.

I posted here because you guys seem to know small blocks better.

What double pumper would you recommend? A 750 or should I go larger. I picked a vacuum secondary carb for street manners. I'd like to maintain a slight amount of manners.

The '71 340 'Cuda I had ran 11.70's with a 750 double pumper or a 850 vacuum secondary carb on street tires. It was slightly crisper on the street with the 850 once it was dialed in and was a touch faster on the street too.


I'm open to all reasonable suggestions. :D
