High exhaust / engine compartment temp

[hemi68charger]

Hey gang..
Well, I'm getting the Daytona out and about now. Something I've noticed is the high exhaust / engine compartment temperatures. I know running around in 100 degree Houston weather isn't helping much, but never had this with my '69 Charger 500. The left side has visual evidence in the white tube loops that hold the windshield washer tubing on the passenger side have melted. I'm thinking maybe it's a lean condition? I know Daytonas and Superbirds run characteristically hotter than other cars because of their restricted air flow into the radiator area. The carb that's on it now is a Edelbrock Competition series with electric choke and the ignition is Mopar Performance electronic. The engine is a 440 with 9.7 compression and is followed-up with a 727B

Thanks..
Troy

Troy,

You may have to go the route that most everyone else with a daytona or superbird has,  put an electric pusher fan hidden in the nose cone some place.  Lets face it, those cars were not made for going 25 mph or around town!

I Jet-Hot coated my manifolds....brought the temps down considerably in the engine compt

Not necessarily so.If everything is as it was when new,there should be no problem.Regardless of what the outside temp is,mine has never run above 195 regardless of speed.One of the biggest factors that contributes to overheating is the missing seal between the bottom of the core support and K member.

The water temperature really doesn't seem to be running hot. My gut is telling me it's a lean situation. As 62Max states, it shouldn't be to the point where the inner fender area gets so hot that it melts the washer squirter hose white hoops and causes the master cylinder to get so hot it's causing brake fluid to seep. To me, it's heat being generated by the exhaust manifolds. Does this make sense. I mean, I remember seeing lean situations causing tube headers to glow red.

I'm going to pull some plugs tomorrow to see how they look.

What is the model number on your carb Troy ? The electric choke Eddy carbs are notorious for being lean.  

A lazy timing curve will also contribute to high exhaust temps....it could be a combination of both.

Hey Ron,
I took out the plugs this morning prior to going to church and they have the gray look to them as burning normally. So, my theory on being lean is incorrect. Here's what I added to another Aero-thread.... It seems to be an engine cooling problem.
