I owned a 1980 Buick Regal which had carbs, no oxygen sensor or fancy
electronics, but had a catalytic converter. The cat-con did run hot, but it
also ran for 8 years and 165,000 miles, including highway, autocross,
towing, etc. without burning anything up.
Over the years I adjusted the mixture (pesky little plastic caps), idle
speed, distributor timing curve and just generally put the beast through a
lot. Not a single hickup from the cat con. It may not have been doing much
after 8 years, but it never gave me a problem.
BTW - I also had the infamous Chevette tranny in this Regal and had no
problems with it either.
Later,
Jack
