Old time 500 cfm 2 barrel

[cargoil]

Does anyone remember an old Holley that was a no choke 2 barrel 500 cfm that had several gas ports surrounding each venturi? I had one on my 140 hp Corvair buggy and loved it. I'm talking back in the 70's. I would love to find one for my 63 Corvair with it's new 140 engine.

I remember them well! Had one brand new on a '64 Chevy Carryall with a 327 in it. Worked well, and had fantastic low end response on my 327, but wasn't enough carb for higher RPMs, so I swapped to a 4 barrel 650 Holley later.
