I have a 77 K10 with a 350 and Edelbrock carb. When I first bought it, I had to drive it home on the freeway for about an hour. It kept doing the same thing - just felt like it was running out of gas. I did EVERYTHING to the fuel system - new pump, removed both tanks and replaced sending units, I mean everything. But it would still bog down at freeway speeds. The last thing I did was rebuild the carb - after taking it apart, I found a bunch of crap inside that was blocking off the flow. After cleaning that and rebuilding, it runs great on the freeway now
