Thoughts on Hood Insulation
Our first 67 didn't have hood insulation. That was when I drove 45 mins one way daily.
In the summer a sudden rain shower would cause a back up on the interstate.
The steem that would rise off the hood while crawling along with the crowd was quite embarassing.
If you haven't had mice or squirrels pull the insulation down for nesting material under the throttle linkage, there's no reason not to have it.
