Have not been on in a while cuz i sold my van. But I now have a new one! here it is..

Its a 69 108 with a 318 and three speed tranny. 2 bbl carb. I am having a weird problem that just started.. when I drive at normal speeds it runs and drives fine lots of power no problems at all. But one I get on the highway at speed after like 5 to ten min then it starts to die. I can pull over and drive slower and it will run fine again and go as long as I want. but the min I try to get it back up to hyway speeds again it starts to die???

I have replaced
carb
fuel pump and filter
fuel lines
coil
wires ,plugs, points, condensor
alternator, battery

what else could be causing this? anyone else ever have this problem?

thanks
our vans have a five sixteenths fuel line from the tank to the carb. this is insufficient. replace with a three eights fuel delivery line. problem solved !
