Haven't been following this thread so don't recall what engine you have but
sounds like it has gears rather than chain timing set?  If that's the case
then that is excessive clearance but should not cause rough running.  I had
a 429 with a chain that was litterally falling off the crank and it ran
pretty well until it actually slipped.  When I took the cover off it was
hanging loose below the crank so that the teeth were just barely making
enough contact to drive it.  What loose timing ususally causes is spark
scatter which can affect the total performance at higher rpms but usually
doesn't cause trouble at lower rpms that I've noticed.

Rough running is usually a vacuum leak or misadjusted carb.  It can also be
a badly worn carb in the throttle shaft area or a leaking gasket in the carb
or base gasket or egr valve etc. If this is an early engine it may not have
an egr.  I believe those came out around 68 or so.  It could also be the PVC
system if it has one but again, older ones had the down draft vent instead.
If it has points these could be pitted or the condenser could be bad or the
coil could be leaking or....or....or.....  Problem is there are so many
things that can cause this.

Has anybody out there put a 302 in a '52 F-1 with the original straight
axle?

Any thoughts/ideas about mounts, etc would be appreciated.
