The Air Grabber is the best

  1. Never seen one of these. Did it do any good, or was it one of those '+0.5 hp (maybe)' wonders?

    1. It'd flow a little more than the 750 cfm Carter 4-bbl carbs that came on the regular 440. The thought expressed to me is that normal driving ran the off the center 2-bbl carb (enhanced fuel efficiency) and then the full 6 opened up when you really wanted to show off.
      What I noted is that the stock cast iron intake manifold was hideously heavy and constricted, the aluminum manifold I had with my 6-pack (definitely not stock) was way lighter and flowed much better. Any horsepower improvement probably came more from the manifold than the extra carbs.
      However, some old-timers maintained that the 2-bbl carbs flowed "faster" than the 4-bbl, but I never understood why they thought that. I got about the same speed with an Edelbrock dual plane aluminum intake and a massive 900 cfm Holley 4-bbl, except that damn Holley leaked like a sieve. So the 6-pack, in my experience, was mostly bragging rights and showing off.

    2. Carbs are tricky things. They Deon engine vacuum to work. Opening up too big, too quick, the engine stumbles. (Dodge 318?)
      I had a Chevy 350 I built with the help of an experienced mechanic. Tried 3 different 4 bbls. Never quite ran right. He gave me a single barrel he had built for a circle track car.
      That engine became a rocket.
      It’s all in the balance!

  2. I watched something a couple days ago, (can't remember if tv or net) where a Superbird was appraised at $200k! I wish I had my dads' 300G.

  3. A guy I worked with over 50 years ago had a 440 '69 Charger with a scoop. It operated by a motor with the switch on the dashboard
