I'm selling my 550 cfm carb base  air horn inlet (velocity stack) that used to mount to my hood scoop.  Just rivet it to your hood scoop or tray.  I'm also selling a dominator inlet as well.  I used to use one scoop tray when I wanted to switch between carburetor types so I would just swap the these velocity stacks.  Made from aluminum.

I'll ship USPS or UPS ground.

4-1/4 " tall

5" diameter at carb

6-1/2" diameter at mouth

12-3/4" diameter at mounting base
