Cold air intake ideas for vintage cars and engines.

Not as pretty but works. No issues yet sitting in traffic when it gets in the 100's. Robbed the aircleanner and air conditioning ducts from a 74 Dodge 440 motor home some years ago. The holes in the radiator support provide the fresh air. It is not a sealed system it probably does not pull as much cool air sitting still as it could. The last picture is a "one day" project. See the lines in the dust? I have the idea of setting up either a Cross Ram or dual quad scoops staggered in the Slick era hood lines.

  I’ve heard many people state their engine didn’t run properly in traffic on hot summer days when pulling air from the engine compartment.  Installing a system that pulls air from outside the hot engine bay fixed their problem.

I had the 427Fairlane hood sealed around the aircleaner on my 67 Ranchero, it was effective but even on a hot day the car would stall and the carb freeze up after any highway use. I had to leave off the air cleaner seal and get rid of the automatic choke to be able to drive it.

That sounds more like Vapor Lock

Getting underhood temp down is the ticket when sitting in traffic. Sure the cool air intake is some what of a help so is insulating fuel line , electric fuel pump back at tank. I'm not that big on ceramic coated headers, but they say it helps.  Remember when we use to put the washers between the hood and the hinges for a gap at the back of the hood to let that hot air out?  Keeping the fuel cool is the name of the game especially with ethanol when sitting in traffic on a hot day  maybe try a Cool Can or look into Fuel injection kits....JMO

no pics (because I am still working on it and it is a disgusting filthy loathsome mess, and I am ashamed to show it ) but I am piecing together a unit to be reminiscent of an OEM Boss 351 unit. I am using a '70 4v Cleveland base with the snorkel (but the flap will be fixed closed) and a swap meet 14" aftermarket lid that has similar contours to a sixties autolite open element air cleaner like on a 271hp 289. Still figuring out what I will use for a seal, its going in a '67 Falcon with a bogus Boss 351. Putting a re-pop '69 Mach 1 hood scoop on it. Getting the seal right will probably take some fudging, intake is a Torker with a 1/2" shear plate, so its a bit taller than most of the intakes used on the OEM Ford set-ups. Once I get all the pieces all purty and painted and de-scuzzified, I will post a couple pics.
