If the bushes on the rear tie rod are rubber they could /look /OK, but
actually be pretty soft (I went with urethane bushes years ago). That,
combined with weak motor mounts could allow the engine to slide forward
on hard deceleration.
If you watch them while you rev the engine the blades on the fan will
flex just a bit forward. That, combined with weak bushings and/or mounts
could cause issue. I presume you mounted the radiator as far forward as
possible?

run of twenty miles produce an overheating radiator with fluid
spewing from the overflow tube. To my horror, I saw that the
Texas cooler fan which I'd had for at least 25 years had
confronted the engine side of the radiator leaving a distinct
circular impression and abrasion to the tip of one of the fan
blades. That radiator was rebuilt two years ago with an extra
series of cooling tubes and had given no problems for at least
5000 miles. I assumed the harness which prevents the engine
from sliding forward was faulty. Inspection of the underside
did not support that conclusion--it looked fine to me: all
bushings and nuts were in place. I ran the engine after
filling the radiator and saw no evidence of recurrence of the
fan nudging the radiator. I'm perplexed what to do next.
Thanks for your thoughts......</div>
