What does everyone use in the engine bay with the 3800sc swap? Do I just buy a new stock fitted one? Couldn't find anything on this thought you all could help thanks guys.

I used the foil backed insulation from WCF for the last three swaps. Two of them were 3800 SC engines. Similar material should be available from places like Lowes, Home Depot, etc. or maybe a local hardware or auto supply store.

Lizard Skin
Dynamat
Generic foil insulation like WCF sells and is available at a marine supply

Or nothing. Plenty just have painted engine bays, and a bit more insulation on the other side of the firewall, or between the main firewall and sheet metal overlay.

Firewall and the shock towers. With no insulation there may be a slight increase of cabin noise. I don't think engine heat and the interior is much of a factor with or without the insulation on the firewall. IMO the insulation was more for lowering noise levels. Opinions?

I used carbon fiber welding blanket, which you can get here. Withstands temperatures to 1800 degrees F.
You can get a template from fierosails.com for cutting it to shape.

I've not got mine done yet, but I've definitely seen comments from others who have stripped the insulation and not added additional insulation on the other side of the firewall, who have reported definite heat radiation increase through to the passenger cabin; and comments where adding dynamat or such on the interior side definitely helps reduce heat as well as noise.

This is what I use (1/2" thick version). It has multiple layers for both heat and sound control and has significantly more mass (and more expensive) compared to other material you can purchase locally.

WEST MARINE Noise Control Barrier Material


I was reading reviews of the product at the site you linked to. There seem to be multiple complaints about "separation" of the layers. Have you experienced any such issues?

With these insulation choices, whichever you prefer, with a 3.8 or LT1 swap
are you eliminating the metal shield and these materials withstanding the heat?

I was looking at a small air deflecter to move some of the airflow beneith the
body up through the already vented hood area.
I'm considering a turbo 2.8 or an LT1 swap in the future, both of them in the shop.
Just looking for input.
Make any sense at all? Lol

I have used Dynamat/Fatmat on the exterior firewall and interior firewall and then added the foam floor squares pecies they sell at Home depot for garage floors on top of the mat on the inside firewall ...it all works great together

these are the foam squares I am referring to



Would love to do the next engine bay with that lizard skin though.

I'm going with spray/brush-on sound dampener and insulation, and swapping in an LS4.

Any auto body supply shop should have some "hood insulation" - same stuff if you are looking for something along the original looks, just cut to fit.

Here is an eBay link: http://www.ebay.com/bhp/under-hood-insulation
