Underhood Temps
We've had a bit of a heat wave up here in the Pacific NW and my truck has not reacted well.
The truck is a 84 F350 4x4 crew cab with a 460 and a C6, 4.10 gears, lifted a bit running 35's. Factory exhaust manifolds, and a open element air cleaner on a Edlebrock carb. Coolant flushed and system pressure checked.
My issue: My temp gauge normally runs at about the approximate 1/4 to 1/3 area when running down the road, whether the truck is loaded or not. When stopped in traffic, it will creep up the 1/2 position, but it has never gone above the 1/2 position. However when I sit in traffic for an extended period, my idle drops, gets lumpy and acts like the engine wants to die. I end up driving with both feet to keep the rig from shutting off which is a PITA in certain situations. The underhood temps get HOT and I'm curious if that is the cause of my problem.
I have read in places that the 460 generates some serious heat. I'm curious if I'm experiencing vapor lock or something similar? Or is the engine starving for air since the open element air cleaner is sucking in very hot air (maybe some type of cold air duct would help)? Since the temp guage holds steady and doesn't overheat (and my system pressure checked okay), I'm wondering if I need to do something to get rid of the hot air underhood? It got hot enough last weekend while sitting in traffic with the boat hooked up to the truck that the plastic ring that holds the aircleaner off the carb started to deform.
Any help appreciated.
