heated O2 sensor number for 350 TBI truck?

[KasaRyan at aol.com]

I tried converting my 383 TBI truck to a bosch 12009 O2 sensor with disatrous 
results.  I have since found that it is for 88-90 AMC products - so you just 
know there has to be something wrong with that.  I believe it works 0-400mV, 
not 0-1.0v like the factory GM sensor.  The heat is on a relay driven by the 
fuel pump relay - so it has power whenever the engine is running.  It came up 
with a value in only about 15 seconds - but it started at 100mV and never 
went over 250mV at WOT. - So it went immediately into closed loop and started 
adding fuel.  Once it got to 160 on int and BLM it went open again since the 
number was obviously bogus.  Really bad driveability and mileage.  Took it 
out after a half hour of checking other things, connections, etc.  Put the 
original one wire sensor back in and everything was peachy.  Ok now - what is 
the number for the Bosch sensor I do need that has the same parameters as my 
stock one wire?
Also tried changing from 160 therm to 180 therm with 1/8 hole drilled in it.  
Runs fine - but can see 1-2 deg retard at wot around 4500 - can't hear any 
knock - is this acceptable?
Thanks for your help
