1964 C10 troubles

[rmsteph828]

Hello everybody.

I am having some bizarre troubles with my old girl. Its a 1964 Chevy C10 long bed step side with the original 230 engine and a muncie 4 speed. She was my daily driving till I started college and moved to a colder climate, now she is my weekend ride and hauls fire wood.
My problem started one night at 2:30 in the morning driving home from a party (it was about 20 degrees out). The truck would idle beautifully, i started to head home and made it fine on the flats. Once I began to climb a moderate grade, she would start this chugging and lurching till she would die. So I would pull over, wait and curse for about ten minutes and she would start again and run great through any flats and then die at any hill. Also if i romped on it through the flats the same problem would occur.
Using my reasoning skills I assumed it was the 1bbl rochester carb float handing up. So rebuilt that with all the proper measurements, nothing was out of place. But I still had the same problem, so this time once she died I pulled off the top of the carb to find the float dry (1/4 inch of gas was left) . So now I have my self a fuel pump problem. Pick up a new one, replaced it only to find deep groves worn in the cam in which it rides on.. not to much i can do about that, but it could be the culprit. With the new pump in place the problem still occurred. So out of sear desperation just started testing and cleaning everything. did a compression test, 125-130 on back five cylinders and 110 on cylinder one. I cleaned and tested, re set point on the distributor. I replaced the vacuum advance it was shot, and retimed her to 4 degree TDC. I also found the PVC Value to be making a racket, when idling the bearing with in it constantly spins. I plan to replace it today.. but I still have the same dam problem...and I need help. I believe I have it narrows down to worn cam or old clogged fuel lines. Any suggestion would greatly help

Thanks
