Advice, help me put together a big summit order...!
Just wondering what you guys recommend for a good dual plane intake that with a carb and filter will clear the stock hood on my 1976.
I would like a holley carb. I was looking at the Street Avenger 770. I have a mild 383 in a 1976 with TH350 auto trans and stock gears (i think they are A/C gears because my car is an original factory AC car).
What brackets and other items do I need to make everything work with the car and kickdown cable for the trans? Thanks for all the helps. I already have an idea of a few parts but just want to make sure that I dont miss anything. I also read I should stay away from Summit Fuel Chrome Fuel Lines any advice?
Is this the correct kickdown extension that I need ?http://store.summitracing.com/partde...5&autoview=sku
Thanks guys.

Edit: I don't care about the stock air cleaner. I just need to keep the clearance under the stock hood. Just want best power I can get from manifold up under the stock hood with good streetable setup (reason for going dual plane and thinking the Holley Street Avenger is a good choice).

Your selection is limited if you want to keep it under the stock hood with the stock air cleaner. If you use an aftermarket drop base air cleaner, you open up the options.
If you need a low rise, you are pretty much limited to the Edelbrock 2101 or the Weiand Action+. Of course you can always go with the Professional Products, which is a 2101 knock off.

I'm running a Holley SA 570 on an Edelbrock Performer EPS #2701 (which is slightly taller than the 2101). I have ~3/4" hood clearance with a K&N 14" X 3" on a 7/8" drop base.
Just curious, but what kind of RPMs are you planning on running? 770 cfm seems a little large for your application, according to Holley's formula.
Good luck

I had a 2101 intake and Holley 750 on the stock 72 motor for a couple of months last Summer. I think the carb may have been too much for the stock motor but there was a very noticeable increase in torque, probably due to the manifold. The clutch started slipping when accelerating hard after the new manifold/carb was put on.

I'm not A Q-jet person but I think they were at least 750 CFM,
I do know they were used on 327/350 low rpm hydraulic cammed
engines, most had automatic transmissions. If a 750cfm carb works
fine for a 327 low rpm engine, auto trans, with highway gearing.
why go smaller in CFM for a 383 size air pump ?? High rise dual
plane manifold, 770 VS avenger

Little Mouse is correct, Q-Jets are 750CFM. There were some that had larger venturis that were rated somewhat higher, but these were limited in application and much less common.
As for the Edelbrock manifold, Ganey ahs posted some great information in several older threads relating to the three distinct generations of Performer. The second generation is apparently the one to get as it is said to perform as well as the Chevy high rise. It is distinguished by the Edelbrock logo being on the cylinder runner behind the thermostat housing and not on the valley of the manifold. If you search for one of his posts, he links to a picture.
I found a second gen performer for my project on Craigslist locally for about $75.
Good Luck
