I had a 360 in my 86 conversion van. Whenever I stopped, I had to open the hood or it wouldn't start....Not to mention the goo from the back of the ECU dripping.......BTW, it had a Quadrajet.
This is more symptomatic of "vapor" lock; and while it is evaporation, it is not the same as cold start issues due to potential fuel evaporating from the bowl, over time.
