Lack of Power

courtesy of Bob, The Auto Answer Man

My 1991 Chevy van with a recently remanufactured 350 is having trouble. After starting up, it idles fairly roughly and loudly. Upon giving it gas, it gets me going ok, but with nowhere near the power it had before it started knocking a few weeks ago. I have plenty of oil pressure and I've been told that because of that, my rod knuckles are ok. The knocking occurs when I'm trying to accelerate or am going up a hill. I've gone on the freeway with it, but the knocking is still there, and the power really lacks. I've changed the plugs, points, and distributor cap to no avail. By turning the distributor clockwise a little, I'm able to lose the knock but I also lose even more power. Can you help me? Would it possibly be an ignition module?

It sounds like the timing is out of whack. I would :
1) reset the timing according to the service manual
2) verify that the vacuum advance is working
3) use higher octane gas
Good Luck!
Drive Safely!
