One more engine question
I was thinking of replacing my tired 2.8 GM engine in my 85 XJ with the HT
3.4 GM replacement, but I found a complete running 4.0 from a 92 XJ. Even
with the cost of rebuilding the 4.0 it would cost me the same amount.
Problem is that the 92 XJ was hit in the front so I can't get decent
measurements to see if I can fit it in my 85 XJ. Anyone know if it will
transfer?
Thanks.

It will not fit. They changed the firewall size for the 4.0.

Thanks for the quick response. Just looking at the length of the engine it
diddn't look like it. I was hoping though, in my opinion the straight 6 is
a better engine than the V.

Re: One more engine question
I agree, since this is my daily driver, I don't want to have it out of
commision that long just to shoe horn the engine in and it would never be
properly mounted.
