i have a 1966 mustang with a later model 302 4 barrel carb. ever since i got it it has had problems with what i would like to think is overheating but im not sure.
When the car gets between around 200 to 230 degrees it starts to lose power, it makes a weird sound when i push the throttle too much, kind of like a stuttering sound and it wont accelerate until i press the gas very little at a time, the engine will also shut off at an idle. this all happens after around 20 to 30 minutes of driving or after a second trip shortly after the first and it will be undrivable until it cools for atleast a few hours.
Ive replaced the radiator, new 3 row 66 radiator, thermostat even taking it out for a while problem still occured, ignition coil, carburetor, intake manifold, fan blade, fan shroud(helped a little but only extended the time before the problem occured), alternator, starter, plugs, gas tank, filters, everything: the problem existed before all of these and is still occuring.
the main thing thats puzzling me is that from what ive heard 302 run hot around 210 to 220 so im curious as to why mine wont function at that temperature.
Any ideas or suggestions would be greatly appreciated, as ive been struggling with this problem since i bought this car and well im 16 years old so its my daily driver.
Thanks!!!
