I think it also helps to keep heat in during the winter... If you drive somewhere, and leave your car parked for an hour then come back to it, engine should might not be frozen when you come back.

How about to keep the heat from the engine compartment from discoloring your paint.

That's what I thought but mine caught on fire because of a backfire.

It might be but seems superfolous, alot of cars run without them without side effects

As was stated at the beginning of this thread, the original and primary purpose was to decrease noise level in the passenger compartment. Now, that doesn't mean it might not also serve to suppress an engine fire, but that is just serendipity. It's like when the wealthy lady showed up at Chrysler Engineering, many years ago, complaining of the poor fuel mileage with her Chrysler. Turns out she found that the choke knob also served as a convenient place from which to hang her handbag.

/\that's a classic. Never heard of it before though, but I'm only 20.

My old car hood insulation was oil soaked, so I was constantly cleaning the engine till I yanked the crap out.

The insulation doesn't do anything for heat absorbtion. Besides, the heat emitted from the engine isn't enough to melt the paint off your hood, or under it for that matter.

One of my rides is a 69 Pontiac Cat wagon and the heat from the engine has warped the hood.

Any recommendations for alternative material? Dynamat? other?

Depending on the car, that heat will make short work of your paint. Many Impala SS guys have taken theirs off only to be dissapointed with huge spots of destroyed paint immediately above their exhaust manifolds. I've done some damage to my 73 station wagon hood. It didn't come with insulation and the headers I have in there are starting to cook the paint.
