Mike,
WOW! I think you may have hit the jackpot.
One of the previous owners had the cylinders over-bored by 0.030. I
only thought about the minimal displacement increase (< than 289). I
don't know much about the differences between a 260 and a 289. Aren't
they the same block?
I know the 260 claimed to use "thin-walled" casting technology. Have
any of you had a 260 bored?
This thing is getting real interesting for sure.
I called a local radiator service company yesterday and they quoted
$185-$225 for a copper 4-core modification to my radiator. Does this
sound about right? They'll also add a drain plug which I sorely miss
everytime I do anything with the radiator.
Thanks,

<< I got lots of expert advise at the event (thanks guys). Replace the five
blade
(stainless steel fan) with the Ford 6-blade std. steel blades (must be
trimmed
and hole enlarged). Put a 4-core radiator in, or have mine re-cored (any
personal experiences out there). Take all the HI-PO stuff off the engine
(headers, cam, 4-barrel etc.)...ouch! Block the holes around the horns (done
-
no noticeable effect).
Bottom line is that I think my efforts are not moving me forward on this
problem
(maybe backwards). >>
Frank-
I think you're right when you state at the end of your post, "I'm still
convinced it can be turned into a reliable cruiser". My Tiger used to run hot
with the, basically, stock 260. When I dropped in the Motorsport 302, I also
had my radiator re-cored with modern technology. Now, with a 300hp motor, the
car runs at 180-185 all day long and only creeps up to 220 in traffic on a hot
(95+) day. This is pretty good, considering I run a "flex" fan (which I've been
told to junk) and no other cooling system related mods. Short answer: Have your
radiator re-cored!
One other thought: Do you know if your block has been bored out? Anything over
.030 is a definite recipe for terminal temp control problems and some castings
can't seem to even tolerate .030 in the Tiger environment.
