Bennett,
I am looking at adding an electric fan to keep air moving thru the
engine compartment after engine shut down. What I've noticed is after
the car has run at temp, and I shut it down, I have:
1) problems starting up - seems like the heat build up affects the carb.
2) Engine runs rough till it gets back down to its usual 205 - 210
degrees - believe that the built up heat affects the distributor also;
the tach readings are really off until the engine temp gets back down.
Any recommendations? 1965 '2096 Tiger, 289, custom radiator, Holley 4
barrel.
