1973 340 functional factory hood scoops are on the car. Does anyone make a system to close off the air cleaner from the engine compartment allowing the carb to suck air only from the hood scoops and not the engine compartment (similar to a factory ram-air system on the roadrunners)??? Thanks guys!
 
I don't think anyone makes a specific kit for your application but, you can make one or have someone else make one if you lack the fabrication skills. It
won't be too cheap though either way.
 
You can make a tray to seal the carb to the hood, but all my testing taught me those low scoops that far away from the front of the hood don’t get much air after about 70 MPH.

That’s an awesome job creating a very clean cold air package! I didn’t read all through the thread, so if you’ve already commented, please excuse me for re-asking. Have you noticed any performance increase both at cruise and wide open throttle and did you need to do any re-jetting on your carburetor?
 
Look up photos or contact Steve, OldManMopar. He had an awesome setup on his old car

Is this how ya do this? @Oldmanmopar

I can't say there were any performance increases because I never did any A/B testing. It definitely brings cooler air into the carb so depending on your set up you may need to re-jet.

Make sure you design some way for the water to get out.

I drilled a 3/8 inch hole at the low point in the pan. I found the low point using a small ball bearing and rolling it around the pan. I can also say that I have driven the car on long road trips and ran through some rain storms with very little water getting into the pan, maybe 1 ounce of rain water. This is because of the design of the original scoop and factory raised rubber "gaskets" that fit into the two round openings in the hood. A different hood scoop or large opening in the hood would probably allow more rain water in.
