My '77 5/4 ton Dodge had a Carter 2-barrel on the 318. Once it got anywhere north of 80* here it could vapor lock at any time.
So it VL'ed on me one day, in rush hour, on a two-lane street that has a center turn lane. Stalled out not quite a block from the light, so I was able to coast into the center turn lane and stop. Cars going my way were backed up to well past where the truck was sitting.
After waiting a few minutes I tried cranking it, it still didn't want to start but it was a new battery and I thought "Just keep cranking!"
After a couple of minutes I could feel it catch, which meant "Keep it floored brother!" Looking in the side-view mirror, there was a Ford Escort wagon, driver's window down and ON the car's bumper in front of him.
Big fat 3" diameter solid black jet of smoke right in his window with a big "CHU-CHU-CHUG-BBRRRAAAAAAAAAAAAAWWWWWWW!!!!" <lmao> Like I was going to let it die after that. <dontknow>
