I read on ls1tech that they did not go to DBW on the 5.3 until 2003. I don't know I'm just trying to learn. Another question how can I find out what year the engine is?

+1 I was always under the impression that DBW didn't start on the trucks till 03.
Simple way is the vin.

Traction control trucks had DBW, also some tahoe/subs' had DBW


look up for example SPoolin on PT.net and his Kermit. his i believe is a 01 that had traction control with DBW

Looks like you know your stuff. I just looked up the PCM and its for a 2001-2002. The number on the PCM is 12200411. The guy I got the engine from told me it was out of a Tahoe but he is not sure of the year. Well the PCM at least narrows it down to either 2001 or 2002

Well I'm going take you guys advice and use it in my 55 Chevy Truck. I just purchased some books to learn about these engines, so I will be doing a lot of reading. I don't like nothing stock so I will be checking out how I can put some attitude in this little engine.

whats needed to make a 5.3 a 382? Or for that matter, what can a LS1 be stroked to? I just happen to have a 5.3 and a LS1 (LS1 has a bad bearing it seems) just sitting around. :thanks:
