47-55.1 Exhaust manifold temp

[nvrdone]

Hey 1 Project: Thanks for the info. Its interesting to see that the corner intake temps are fairly consistent. The center exhaust temps seem high so thats what started this whole line of questions. That and the truck sat for about 3 years until I retired an had time to play with it. FYI the distributor is an old Mallory dual point that was converted to Petronix ignition. Ignition is set at 10 degrees advanced. The engine idles well at 950 rpm. Valve adjustment is next. Maybe this weekend. Also double check the idle mixture. I think I would be happy if I could get the center exhaust temps closer to each other.
The engine still runs strong for having been built in 1973. But then maybe its time to switch to a 392 hem !!. But I'm only dreaming !! Thanks for the help.
