" down, not up. 

btw the amc 2.5 uses the same mounts as the straight six and with the
right bell would bolt up to the spirit sr4/t4/t5.

gremlin/spirit fours ran 3.54s iirc.  you could probably run 3.31s if
you pick your cam and maybe even 3.08s at the sacrifice of a lot of
performance.  you'd have to swap cams though as jeep went the other
way, emphasizing mid/top power to make that little four move a heavy
boxy wrangler.  the 4.10s show it, even with a 3.93 1st.  sixes could
have 3.07s, in cherokees at least.

i've heard that in jeeps there's little or no mileage difference
between fours and sixes, because the four has to spin faster and work
so much harder.
