First year for 5.3L 285hp V8?

[Gripenfelter]

What was the first year that the 5.3L 285hp V8 was available in the Tahoes and Yukons? Was it 2000? 2001? 2002? I know the body style started in 2000.

Don't know for certain, but didn't it come out in 1999 1/2 ?

Yep, as long as its the same as the silverados. I had a 99 1/2 pickup with it in there, along with the new body style.

Guys I am not sure about the HP when the 5.3 first came out. Wasn't it 270 until 2002 and then it went to 285?

It was 285/325 in 2000.

The 1999 tahoe had the 5.7 as a base engine rated at 255hp. the 2000 model year tahoe (which I think showed up as a 1999 1/2) had the 5.3 rated at 285hp and good for 325 ft.lbs

Edit: opps, looks like I was a little slow on the draw (busy watch Ohio State crash and burn)

2000 sounds right, as I know my 99 is 270.

Yeah, its 2000 as mine has the 285/325.

Yep,2000 was the first year for the 285hp 5.3.

Also the 4.8 was bumped up from 255 to 270hp,This was done by GM putting in the camshaft from the 6-liter.
