Yesterday this car was running sweet.... Today I have to keep the gas pedal down to keep it running.After doing this for about 3 minutes, smoke starts to roll up from behind and down below.the distributor.
If I get underneath the carit looks like smoke is coming off the whole exhaust, not out the exhaust. I can see nothing leaking on the exhaust to generate the smoke. I really have no clue what it is, and just threw out a guess that it was the converter.

I think Mad Mike is correct
Oh, so do I, I just didn't want him to be. This is a welded exhaust front to back. I just didn't want to drop the downpipe. It's either that or gamble & sawzall the pipe in front of the converter. I'll drop the downpipe
