203 Part Time Kit question

[swissarmychainsaw]

I recently picked up a Suburban '76 K10 and it has a 203 in it with a mile marker part time kit.
(I also own a '73 truck with a 205 in it)

What I noticed is that with the 203, I can put it in 4x4 and still drive it on the street.
With the 205, you can really hear and feel the front tires scrubing when you turn them on the pavement.

Is that normal? Does the 203 with part time kit not make the front tires scrub during a turn?

Thanks!
