Thoughts on hood insulation
Does anyone have any thoughts on hood inuslation? Most of us probably don't run any (I don't) but I would like to know your thoughts if you do; what you are running how you installed it, how much it cuts back on noise. I am considering installing some on my '67.

Re: Thoughts on hood insulation
You might have better luck with some self adhesive stuff like Dynomat, I bet it would make a big difference in reducing engine noise, our hoods transmit a lot of sound, even with new cushions between the braces and hood. I think Dynomat would work better than insulation and you won't have to figure out how to attach it.

Re: Thoughts on hood insulation
If you're looking to quieten down underhood noise,you might consider having the inner wheelwells and underside of the hood bedlined.That should last well and cut down a lot of noise and the tinny sound.

I did dynomat and am very happy I would say bed liner on the tubs would be good money spent.

Re: Thoughts on hood insulation
Hey there Dan!......how things been?
I did the bottom of mine and think it was a good move.....really quiets down noise from engine, gives a real nice "thud" when you close it, and it also minimizes hood shake (driving down the road and you see the top sheet metal of your hood wiggling around). I used a single side foil back insulation and attached it using a 3M hood insulation spray glue......sticking real well after 3 years. Also used something called stack tape around the perimeter....it's a foil back very sticky tape used in the HVAC industry. I did it in 2 pieces with the seam under one of the braces....took some larger sheets of paper and cut a couple templates. Just slid the cut pieces of insulation under the braces which was nice and snug. I also ran an aluminum strap along the hood ridge just to insure the insulation stayed up. After I got it all up, I didn't like how reflective it was and took a scotchbrite pad and scuffed it all down real well to dull it up......looked better that way to me. I think it ended up looking pretty good and was pretty inexpensive. ![]()
