under hood temperature management

[yevgenievich]

What does the front of your radiator look like?

Radiator is relatively clean, otherwise it is busy in front. Not overheating, but it is very warm under the hood. Driving in traffic today in the heat, intake air temperatures reached 170*F

Have you thought about the Roadkill approach and just take the hood off?

Too bad they don't list a source for hood and bumper

I was thinking this was going to be a problem on my squarebody too when I swap in the L29/4L80. I was planning on modifying the stock passenger fender to use the GMT-400 style intake and pull air in from in front of the radiator through the fender. It mostly looks like it will involve closing up existing vent holes in the fender, rather than opening anything up. I know it won't help with under hood temps, but it would help with IAT... and that's the more important thing in my mind.

Seeing how flat the OBS hood is and how low the engine sit I've been eyeballing this drop vent from AJ Hartman.

X2. Now we're getting somewhere

So, I've been thinking on this same issue for the last few years. I've looked at those add on louvers. Aircraft NACA ducts. Even though if grafting in some Buick GN fender, or GNX fender outlets. Saves cutting the hood. Also 70's Trans Am has a fender outlet. Just another idea, that would not involve a lot of hood rework or structural compromises.
I thought the back of the wheel well area outlet. And out through the fender at a point about half the door height.
I was thinking " I'll just make a path of least resistance. The air down the side would have lower pressure therefore the higher pressure under hood air would drawn to the easy exit. Just a thought.

If you could find the 70s Firebird T/A or Formula, or Camaro Z28, front fenders with the vents, IIRC they are about the right curvature. And having the fender would give you the mounting surface too.
