Modded l98 hot as ***** underhood?
I know everybody says corvettes run hot and whatnot.. but my car just idling on a 70* day w/ my hands by the brake booster is EXCRUCIATINGLY hot. I mean, holy damn... HOT.
Is it simply because of the mods and LT's?

hehe. But you really think that insane heat wave is just my headers?

Headers could be contributing to the heat. The C4s have a sealed engine compartment. There is simply no where for the air to go except for around the underside of the motor. The clamshell hood is sealed to the firewall and around the wheelwells. When I carbed my C4 years ago, I had a bad problem with fuel perculation. Even with ducts cut into the hood, the problem still did not resolve. That's one reason I went balk to fuel injection. And yes, I tried wrapping my headers.

Actually air is pulled in through the radiator, flows across/around the engine and out through the "gills" behind the front wheels.
Indeed a coating inside/out like Jet Hot will reduce exhaust heat flow into the engine compartment. I had coated FL headers on my prior IROC-Z and I could almost lay my hand comfortably on the headers..
The inside coating is particularly important as it tends to keep the heat in the exhaust gas, just where you want it.

I can't find it right now, but I remember reading of a member removing the seal that runs along the top of the hood/top of firewall and he said it helped lower the temps under his hood. I haven't tried this yet, but I am also noticing my carb makin' coffee. May try it this spring. (after I get my ball joints, poly bushings, f & r wheel bearings, shifter, 383 swapped in...)
