Didn't GM continue calling the engines Vortec in this series? Like I said, never owned one but I've seen plenty of LS engines that said Vortec. But we refer to them as LS and the GMT400 one Vortec to differentiate from TBIs.
I'm not sure the 4.8 wasn't a good idea. Not much smaller than the 5.3, only used in lighter trucks, more power than previous 305, and fantastic mpg. Also, as mentioned, served to get the entire like under the EPA radar for those who want more power. I'd sure like to be getting 20 mpg these days.
And there are replacements for displacement these days.

I bought my 1989 cheap from a neighbor almost ten years ago and I always thought it had a 350 (5.7) in it.
Then one day I got to looking up codes for something else and discovered that it has a 5.0 (I think) according to the code. I'd have to go look again since I've thrown away my notes. I never noticed any particular lack of power except going up a hill in OD if you don't have a good run at it. It's mostly just a firewood truck for me so it would have been fine with just an old straight six.
The GMT400 is quite a bit smaller than my old 76 GMC. That works out good for slipping between trees but I had to mount my saw box lengthwise instead of crosswise, and the crossover box that fits the square body won't fit between the rails on the 89.
Funny, the newer trucks like my 2016 are
huge on the outside but small on the inside of the bed. I'm not sure what the idea was? There must be something like eight inches of empty space between the inner and outer bed sides!
