Brainstorming ideas for coolant crossover on Air-Gap intakes

AJ/FormS said
I googled elevation Ft Collins and see you are at about 5000ft.
I wonder if you are experiencing Icing in the venturies.
Icing usually occurs at temps closer to freezing, at sealevel, but is not uncommon at temps even above 60*F, depending on the humidity.
A lot of initial timing will cause the butterflies to operate at very small openings,which promotes icing.A large venturi, and or a small cam may also lead to icing. If you have all three,you may have a recipe for icing.
You may benefit from; less initial advance, a spreadbore carb,and/or more cam.This will get your butterflies open a little further, and perhaps minimize the icing.5000ft also needs more Scr. A 9/1 motor will struggle to make heat.
Another option is a heated carb-spacer, like they used to put on certain Fords back in the 70s
Another option might be a deflector to prevent the rad-fan from blowing under the plenum
I gotta tell you tho, The very first winter I had my combo together, I ran it deep into October, with no problems, and no choke. 360/292-508cam/AG-750DP/aluminum heads/ 900ft elevation/TTIs. Timing was 14/34@3400. Yeah it was a little cold blooded for a couple of miles. But a 205*minimum running temp and a thermostatic clutch-fan, put some heat in her in just a short while.

What are your cam specs? Do you know the ICA? How 'bout the compression ratio, or cylinder pressure numbers.

This is exactly what's happening or at least 2 out of the 3, I have a 750 Street Demon on top of my 10.5:1 360 with a tiny 213/220* @ .050" Voodoo cam and the carb does get very cold; noticeably more than my old 625 cfm AFB which had smaller primaries. With this new carb I'm basically driving around with the idle circuit the majority of the time. I did get the bigger carb with the intention of upgrading to a bigger cam so that will come at some point but I can't say for sure when (need to get some 3.55 gears beforehand and I don't really have the $$$). Luckily the carb has the plastic main body which helps and I have a 1/2" wood spacer under the carb.

I have been driving it around with the air cleaner unsealed and it does help a bit but I can tell it still needs more heat in the intake. I looked at small coolers for power steering etc. on Summit which seem promising, I think I'll just get one and figure out a way to flatten the fins on the sides so there's more area to conduct heat to the intake. I already have a valve in one of the heater hoses I use to switch it off in summer time.

AJ is right it doesn't need much heat and any little bit helps, this past winter I got the idea to hit the intake with a heat gun for about 10 minutes before I started the car and as it was running, even a small increase in temp made it run better.
