Hi everyone.
OK I need insight from those who've been around longer than me.

327 with only 4000 mi on bottom end. 0.40 pistons, was honed and re ringed by a friend 10 years ago and sat a long time.Professionally built heads with positive oil seals/ 2.02/ 1.6 valves , bronze guides. Brand new Edelbrock 600 cfm manual choke carb on torker intake. No vaccum leaks. idles very smooth after setting the air/fuel idle screws as directed. unilite dist.

Here's the problem. My plugs keep fouling, but not from fuel. I am getting fresh engine oil on the plugs, and no matter how I try to dial the carb, it smokes out the back terribly such that you cant breathe well around the truck. I know what a good running mouse should smell like out the back, and this is not it! Do I have a bad set of rings? I am wondering if because of all the years that engine sat there, if I should get a fresh short block in and re- assemble the new parts I have. ANY SUGGESTIONS AS TO WHAT IS GOING ON?? HELP!!!!!
