I didn't see cowl insulation any where in the manual for the M38. I do wished that I would have installed some though before I put the tub on. _________________ Tropical Veteran

Would it help prevent heat comig from the engine?
What is the insulation type that you are talking about? _________________ Tropical Veteran

The WWII jeeps had an insulation panel on the upper part of the firewall in front of the driver. It went from the side to near the center. There are a few pictures on the G503 site if you search on firewall insulation.
The original material was some sort of thick cardboard.

Ken,
Any decent insulation will help with noise but heat requires the more modern foil faced blankets. These can be found at racing web sites and aviation web sites. The heat issue is not just the upper vertical firewall. To be truly effective you would need to insulate all the way to the rear floor riser. A third of the heat comes from the exhaust, tranny/transfer up thru the forward floors. _________________ Wes K

Yes I do agree about where the heat comes. From the engine bay and the exhaust and transmission etc. I guess it's practically impossible to shield all of it. _________________ Tropical Veteran

Ken,
You might be surprised how much heat a standard rubber floor mat helps. My '66 V6 CJ5 has an old "jeep" full front mat that covers the floors and transmission hump and goes up past the steering column. It really cuts down on burning feet.
