Yes, another consideration, for sure.
To Andy, why do you want to go to a replacement 260?

One of the issues is the trans that you have. Is it a narrow eared box
like the original trans, or is it a wide eared box that has two sets of
mounting hole patterns? If it does not have the narrow box hole pattern, it
will
not bolt up to the original 260 bell housing. At least without modification
(appropriate mounting holes drilled).
Also, the later trans bell housings for a 6 bolt block have a slightly
larger hole for the trans input shaft bearing retainer to go with the trans
that were used. So if you use an original 5 bolt bell housing, you probably
will have to change the bearing retainer housing on the trans, or machine
out the hole in the bell housing.
Most people have gone the other way, converting from a 260 to a 289. There
were some excellent articles on all that was involved in the CAT Tiger
Tales newsletters in the not too distant past. All the info would apply to
going the other way, of course. I recommend geting ahold of those issues if
you can.

Subject: [Tigers] Bell housing question
Guys:
I'm contemplating putting a 260 back in my Tiger rather than the 289
that's
in the car right now. Here's the rub, though. The 260 I have is clearly a
5-bolt block, which I'm guessing all 260s were, but the 289 in the car is
a
6-bolt block. Obviously, I'm going to have to change the bell housing over
to a 5-bolt unit. Now, if I do that, will my transmission bolt up to it or
not? Can I use my 289 flywheel on the 260? Also, are clutch sizes
different between the two engines? By the way, the 260 came out of an
automatic '64 Fairlane, if it makes any difference.
I'm all ears, guys.I've never had to mess with something like this before.
Thanks,
Andy Walker
