My hood and louvers were already re-pops so I'm not that worried about it... They seem to be getting cheaper and the market over saturated with them anyway.

Re: Letting the heat out. 67 Hood louvers with vents...

If I wanted improved cooling...


...I'd put an air-dam under the radiator support. Possibly with some extensions along the front part of the frame back to the front wheels.

This would create both a high-pressure area in front of the radiator, to force more air through the radiator, while creating more of a low-pressure area under the car to pull the heated air out.

It wouldn't require cutting the hood. No water in the engine compartment when it rains, or when you go through a car wash. No rust at the edges of the hood cuts where you forgot to prime and paint the edges of the holes. No fumes in the cabin.

Pretty-much zero downside.

This appeals to me, but I don't like the look of the chin spoiler. If the louvers on the hood could be made to open and close with a choke type cable, then a guy could control the situation, be it rain or just adjusting the flow of air. Maybe a combo of the operating louvers and a chin spoiler would be even better.

One down side is losing the cool factor these would give...

While I agree that cutting open the scoops would potentially allow water in the engine compartment, I wonder how many people will take their classic Chevelle through a car wash? Most people I know, will not even willingly take their classic in the rain...


Fumes in the cabin?

I have run numerous cars without a hood at all ( including my convertible with no top), and never experienced any errant fumes coming in from the engine either into the cowl or over/around the windshield...

Re: Letting the heat out. 67 Hood louvers with vents...

Oreana Custom Machining has machined up some beautiful billet aluminum 66 or 67 hood louvers. I just sent them a message on FB and asked if they could send me a link for them.

edit: Here you go. These are for a 66 and they have a few pairs left.

Exactly... If you have that much blow by from your engine. You have other serious problems to deal with than cutting heat extraction holes in a hood. LOL
