New affordable Fuel Injection

If they did it right, the air being drawn though the throttle body would keep it quite cool, add gasoline that likes to draw heat and it will stay even cooler. Add your engine fan and I think things will be just fine. Now shut off with the hood closed would be a different story as your bay becomes a good oven, but it's only like maybe 150 degrees? Seem even 60's electronics can survive that.

In the end if you grew up with carbs, why change what your used to. If you grew up with computers and modern vehicles then EFI makes more sense to you. After doing a lot of fuel economy engineering, the biggest downside to carburetors I see is the changing of gasoline compositions to resists evaporation and additives that are all designed to be used with EFI because no OEM is using a carb. EFI will always win in the end and it's not by anyone's choice, the OEM's and fuel company's driven by government regulations drives this buss.

The OEM electronic specs are usually over 100c (212F) for pretty much every electronic piece. So, if all the components are auto related, it should last no problem assuming the components are good quality. I'd be more worried about the vibration being engine mounted personally over the heat.

I have a sequential multiport setup on my car with coil near plug, and that is really incredible. These cheaper TBI setups certainly decrease difficulty, however, you'll remember that you're giving up some potential here. Really depends on what you are going for. I won't have to worry about "wall wetting", the design of the intake for wet flow, or a distributor cap ever again, but then again it cost a lot more. really, really fabulous compared to a carb. 45 degrees ambient and it fires and drives perfectly immediately. I can fix any fueling problem in a matter of seconds, and I can easily see everything the engine is doing.
