WHY?

Yeah...Not sure why the term "Slick" was used except maybe you meant to express how nice my hair looks. If that is the case....Thank you.
The following is what I read about Tennessee weather, copied from a website:

"Severe storms occur infrequently. The greatest rainfall occurs in the winter and early spring, especially March; the early fall months, particularly September and October, are the driest. Average annual precipitation (1971–2000) was 54.7 in (138.9 cm) in Memphis and 48 in (122 cm) in Nashville. Snowfall varies and is more prevalent in East Tennessee than in the western section; Nashville gets about 10 in (25.4 cm) a year, Memphis only 5 in (12.7 cm)."

Again, I can deal with some snow, I just don't prefer to be out in it.

I'm originally from Pennsylvania and currently living in Colorado, that sounds like basically nothing.

In my experience an aluminum intake will transfer enough heat from the engine to keep itself warm as long as it's not an Air-Gap type but that's with small blocks where the intake acts as the valley cover and gets splashed with hot oil. Factory BB manifolds are basically already Air-Gaps so IDK, might just want to keep the crossover open to be safe and run a 1/2"-1" plastic or wood carb spacer.

Then again do you drive whatever that 440 is in when it's less than 45*F outside? If not you can block off the crossover.
