Which application for heated O2?

[angrysnowplow]

OK, I've got my headers on now, and the info I've come across so far says a heated O2 sensor may very well solve the driveability issues I have. Simply, what do I tell the yahoo behind the parts counter I need an O2 sensor for? (Pref. 3 wire)
I even read something on thirdgen.org about someone using one for a 4.3 but I wanted to hear it from someone who has done this. /forums/images/graemlins/thumb.gif

Our '94 Suburban 1500 with 350, automatic, and 4WD has a 3-wire O2 sensor. /forums/images/graemlins/cool.gif The bad news is that the sucker costs about $60. /forums/images/graemlins/eek.gif

Edelbrock makes a 3 wire O2 sensor. Summit sells them with the bung for 49.95. Summit part # EDL-3591. Or you can get the one from your local parts stoe for about 60.00.
