Overall scheme of things no
I took a 72 Nova in on trade years ago where some idiot had done 4.11s running a built 327, 4 speed with 27 inch tall tires
fast from 0 to 65 but from there on screamed
These KJs are so far from that
At say 55 these KJs with an automatic, stock tire size run 1500 to 1600 or so if I remember when I ran stock size back in 2005
with 4.10s it will be running 1800/1900 or so , not that much difference out on the road with overdrive , but overall in town, on hills etc it will run way better
