stinky super six?

no cat. it just smells rich. yeah ive still got that round vaccum deal bolted to the head. all emissions crap is still there. i only kept it all when i did the 2 brl swap because it seemed to be functioning. i have played with the timing and didnt really notice any difference in the rich exhaust smell at idle. i know fender tag says 0* but when i first put it back together i cranked it up. and it was pinging pretty good, it seemed to like 5* except at wot out on the highway, it would start to ping. this motor is all atock except for the 1978 super six setup and big exhaust.
