Need Advice! Do I Need a New Camshaft????

[Atlfan65]

Everything is finally resolved. I threw in a new adjustable vacuum can and everything is running great. After tweaking with the timing, I've settled at 10° initial, 32° total by 3500 rpm (waiting on springs in the mail to get it down to 3000), with the vacuum can adding 13° of advance at idle to limit total cruising advance to no more than 45° total. It's funny how many "carb issues" a good timing refresh will fix! The stumble when giving it the beans is completely gone and it takes off like a rocket now with the 3.73. If you punch the gas from a stop this 65 C10 with a vortec 350 will lay 11's through 1st and 2nd gear and my gas mileage went from 10-13mpg. Next, new exhaust. Considering dual 2.5 inch with boom tubes right under the side steps to get into the bed. The adventure never ends....
