Just bought a 1970 Challenger R/T 440 4 barrel convertible. There isn't any insulation under the hood. Some photos I find have insulation, most don't. Is it necessary from the heat generated?
No it is not Necessary. unless you want it to be there.
Without it the heat of the engine could cause paint fading issues on the hood.
Must be for sound attenuation as well?
