the harwood hood is for show only, it doesnt come open on either side, and if you're looking to get it opened i hope you're a good fiberglass man, because its 2 peices and the parts that need to be opened have at least a 1in. gap in between the two layers... needless to say i couldnt make a shop around here open it anyway hope that helped you out. (it would be nice if it were fully opened though the cowl side of that thing is HUGE in wideness)

 

How about a combination of opening the hood vents and putting in a set of fender vents like OldSStroker suggested? That oughta get some airflow through the engine compartment.

 

I have taken out the scoops on the stock hood already, How would I go about making some fender vents? Simply just cut a whole and put some type of a vent mounted in the opening?

 

I'd think any ram air hood should work. If you got an SS hood and opened it up, it would flow cool air through the bay when you are moving. When i have my car idling you can stick your hand by the ram air scoop and feel the heat coming out of it, and i'm running an SS air box so that has to be blocking some of the heat. I thought the point of a cowl hood was to remove heat, have you looked at them.

 

Cowl hoods are typically sealed to the carb, on an older car with a windshield at a more upright position the base of the windshield is definitally a high pressure area.
There is some debate as to whether or not this is the case with 4th gens due to the windshield being raked so much. If you look at the hvac intakes in the cowling they are raised into the airflow, rather than flush as is typical on most cars. The only reason I could see for gm to do this is because there isn't a significant high pressure area there (at the base of the windshield) to supply the hvac system with air when the car is at speed.
Some people have tested this by tying pieces of yarn to the cowl, the center of the base of the windshield seems to be kind of neutral, maybe a bit of pressure there, the left and right sides of the cowl (base of the windshield) allow air under the hood to escape for sure though. I left about two feet of weatherstripping in the middle and took the rest off. I'd also like to do louvers in the hood as well though.

If the heat really becomes a problem, convert to a front breather setup. My car runs too cold sometimes
I'd like to get that air being rammed through the intercooler,radiator back up over the car where it could do some good though, rather than having the engine compartment pressurized and causing front end lift.
Not really a concern though unless you're planning on spending extended periods above 160mph

 

there is a hood for the 98+ firebirds that looks like the firehawk hood, but has heat extractors at the back of it, maybe they sell one for the camaro that does the same?
