On my 67 w/o factory air, the air coming into the vents gets very hot when the "big block" warms up. I wondered if I could attach a vinyl intake hose and run it from the vent intake to the grill to let cool, rather than hot, air into car. Anyone done this succesfully? Summer is here?

Did someone goof on the vent design or what?!!!Got P***** off with the HOT AIR VENT and left them shut .Be nice if someone has a cure!

You are probably missing one of your hood to cowl seals. Engine compartment heat can come over the top into the cowl plenum and on into the car.

Thanks, I will check it. I didn't think about the cowl. I know there are new seals around the hood. I'll check it out.

Thanks

On my 69 there is a rubber weaterstrip that clips to the back of the hood and a foam cowel seal that gets glued to the cowel. This foam seal is what stops the hot air from entering the cowel.
If you add the cowel seal, make sure the hood weatherstrip does not overlap it. If it does, your hood will not close correctly near the cowel.
It will stick up about a 1/4 inch.

If you're talking about hot air coming into the passenger compartment, I had the same problem on my '72 350. I installed a shut-off valve (CarQuest) in the water hose going from the water pump to the heater core. Shut it off in summer ...open in winter. A friend has a thermostat controlled valve from the factory in his '70 big block.Also, you may want make sure all vacuum hoses are tight...maybe a kick-panel door is not closing properly.

Thanks for the help, guys. I checked and there is a cowl seal (rubber) that attaches to the front of the cowl. There is nothing attached to the hood which closes on top of the cowl seal. The cowl seal runs across the cowl area and ends at the end of the vent area. On each end, beyond the edges of the seal and the vent opening, there is an short area that has no seal. The vent is narrower than the hood leaving about 4 inches of open area on each end of the hood. The catalogs seem to indicate that the cowl seal is one piece extending only across the width of the cowl vents. Looks OK to me. Maybe the problem IS heat from the heater core.
