I am putting LTs on my car this week, I am going to replace my o2 sensors since I'll have the car apart anyway, who makes the best o2 sensors for the LT1, thanks....

I would stick with a stock replacment.
You will also need o2 extenshions when you install them. Or you can take your 02s and cut them and solder your own on. Thats what I did.

AC Delco I hear make good 02s, you'll need 2 for the pre-cat or Longtube 02 bungs and for the rears you'll need a pair of 02 simms.

Bosch 02s are ***** dude, trust me I replace mine under warranty every 3 months....shrugs but they are free..

Brett, he is OBD I.
Z, you can get AC's at most parts stores that sell AC deco, i.e Advance Auto parts, Orielly's, Bosch are OK, but I do the same as Brett, and my wife works for Advance so I never have a problem with warranty stuff

you dont need new 02's...stock is fine, just get extenders. You will want the rear 02 gone however because it might possibly throw a code(even though they have no ability to affect tuning, only to diagnose). Just get O2 Simms to replace the rear and you are good to go.

ahh ok. Well like Gangly said the stockers are probably ok, they supposedly are good for 10,000 miles but it all depends I reckon. Felpro F.A.S.T. pretty soon and I won't worry about any of them at all.
