I currently am running the Summit Autolight/Hollet knock off. They are a very good street carb with nothing wrong with it. IDK how they do for racing and other venues, but on the street, it works great. The jets are in the floor and would require a good bit of angle to uncover. Best part of the latest irritation of that carburetor is that it uses all holly parts.
The Carter/Edelbrock carbs are dry flowed for there cfm rating. I got with Charlie Servidio with a Edelbrock 600, it flowed 600. I also did some mods to it. After some work, we tested the 600 modded carb to a tune of 715 - IIRC. Choke removal, narrowing of the throttle blades, removing the extra bar across the secondary side for choke operation, booster narrowing and contouring. There is more to do with the carb above the air horn like a K&N stub stack and a bunch depends on the base of the air cleaner that you may have. Also the amount of air filter height (taller is better) and the lid, a K&N flow through lid is an excellent addition.
I also run a Edelbrock AVS 800 n a 340. No issue there. Though the AVS II would be a better choice with the annular boosters.
I can see better mileage from the annular booster as well as driving manners. I don’t see a lot though. Just a little. It’s all in the tune really.
I don’t know off hand but does the Weiand Action Plus/Stealth clear of the A/C compressor? Since big HP is not the goal with the set up, this intake has always worked very well for me in the past. The Steakth has the square carb pad, FWIW.
I’ve never seen a 1-3/4 header for the truck line. The mufflers are dyno max units which is really good. Among the best if not the best turbo chambered muffler on the market. The Summit turbo did very well on the Engine Masters cheap muffler test being the best all around and overall. I like them a lot.
There design is a direct rip from the old Sonic Turbos that was a DV design. Yep, David Vizard designed that a long time ago.
