The under hood temperature in my '76 4x4 Chevy Van (G3500 small block 400 Turbo 350 automatic transmission) gets too high when I shut off the engine. Until I replaced the HEI with conventional ignition, the HEI would overheat and refuse to work until it cooled down, eventually frying completely (I got lucky and found an engineer who helped develop the original HEI and he clued me in on this problem).
Now, if the outside air gets above 85°F, when I have driven more than 10 minutes or so, shut the engine off, let it sit for over 5 minutes and under 20 minutes, the starter is so hot that it fails to crank enough to start the engine.
I have replaced the starter three times; I have replaced the ignition switch with a high capacity diesel push button; I have replaced both the battery cables.
I am considering louvering the hood and/or installing an electric fan (with a thermal switch powered even with the key off--the solution GM adopted in later models).
