Engine stalling

I have a 1990 chevy truck, 1500 series - Cheyenne. I had the motor rebuilt last year (13 months ago). The transimission is automatic, and I have not noticed any strange sounds or smells. I have to put at least a quart of oil in it every month but have not noticed any oil leaking or dripping from anywhere. It is a 305 that the machine shop said was bored out. From a stand-still at a stop light or attempting to go up a hill or any time I need to accelerate the engine stalls. It runs fine at higher speeds. I checked and replaced the spark plugs but noticed that the second plug from from inside the truck on the passenger side was covered in what looks like carbon or gumped up oil. What could be causing this?

Hi
this could be the start of a valve stem seal leak, what it does is leak oil down into the combustion chamber and cause the plug to foul, the best way to check this before doing a repair is if the mmachine shop did the whole engine have them look at it, they will probably do a compression test and a leakdown test to rule out any other problems
