Gen 2 Coupe Heat Management

I am running a Gen 2 Coupe with a SBF 347, Atomic EFI, power steering and air conditioning. After performing the following I have I have driven my Coupe in August in Sacramento, CA and have had it set in a parking lot during 100°F days. While it got toasty in the car, there was no surface, including the dashboard, that was too hot to touch.
1. Radiator Shroud: I have AC in my Gen 2 Coupe and found that installing a fan shroud is a must. Based on the cross sectional area of the radiator (353 sq in) and a 16”θ fan (201 sq in) only 57% of the radiator has air flow across the core when the car is stopped in traffic. The shroud forces air to flow across the entire core.
2. Radiator Fan: I installed a Flex-Wave Model 238 fan (3000 cfm) to increase air flow. I noted the air coming out of the fan was getting “jammed” up in the outlet ducting “trough”. Therefore, I ended up punching 13 ea 1⅝”θ holes in the ducting to relieve this back pressure. The addition of these holes also enabled air flow to enter the engine bay which I believe helps cooling somewhat. I installed a pair of air extractors in the hood as well.
3. Sound: Noico 80 mil 36 sq ft car Sound deadening mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening. I applied this product to all interior aluminum surfaces (footboxes, cabin, hatch area, etc.)
4. Heat: Noico Green 170 mil 18 sq ft Car Waterproof Sound Insulation, Heat and Cool Liner, Self-Adhesive Closed Cell PE Foam Deadening Material. I applied this product on top of the sound deadening mat in the foot box, side walls of cabin and the ceiling of cabin. All surfaces were then carpeted. I also used carpet for a headliner instead of the FFR supplied headliner.
According to Noico tech support, the Noico Green 170 mil Heat and Cool Liner should be used in conjunction with the Noico 80 mil Sound Deadening Mat for total heat and sound protection. The Noico 80 mil Sound Deadening Mat is applied to the substrate first, and then the Noico Green 170 mil Heat and Cool Liner is applied on top of the Sound Deadening Mat.
5. Ceramic Window FiIm: I had professional installation of Xpel Prime Plus ceramic tint applied to the windshield and hatch glass. Windshield had 70% tint and hatch glass 5% tint. The % refers to the amount of light allowed to pass through the glass. The hatch glass tint is so dark that it provides enough “security” to prevent looky loos from sneaking a peek into the hatch area. The windshield tint is not enough to hinder visibility. The beauty of ceramic tint is its ability to block infrared and ultraviolet rays regardless of the amount of tint. That means 70% tint on the windshield blocks the same amount as the 5% limousine tint on the hatch glass.
6. Header Radiant Heat Shields: Fabricate aluminum radiant shields and wrap the surface that faces the header with Thermo-Tec Heat Barrier. The reflective surface of the barrier is capable of withstanding radiant temperatures up to 2000°F. The adhesive backed side handles direct and continuous temperatures up to 300ºF. I fabricated the shields for each header from 0.040” Aluminum. The shields were mounted to the headers using common muffler clamps. It is amazing how much radiant heat an aluminum panel will block.
