Zort;
True, a regular Ford 260 should not be bored to 4", however; the
Tiger block with 3 freeze plugs in each side is actually a block that
can be bored to 4" or 289 size. ( or add a 302 crank and you have a 302).
As with any boreing job that you are unsure about, you can always have
the cylinder walls sonic tested to be sure.
If you plan to bore a block then you are not "truly original" any way.
Why not just get a 302 short block from PepBoys or some other
discount auto place. A long block 302 is only $700. It is difficult to
build it yourself for that price. ( Of course if you do it yourself then
you know that you did it right ( or wrong) )
By the way; Ford changed the full pump excentric from a one piece
on early models ( don't know the year) to a two piece on the later
models and the 302. Be sure you get the correct one to hold the
cam shaft in; which is needed even though Tigers use an electric pump.
The Tiger came with both 5 and 6 bolt transmission mounts, only
the very early ones had 5 bolts. There were also three different 4 speed
transmissions, the early Tigers with SN below B-9470057 used a Warner
T-10 with the following ratios: 2.20:1, 1.62:1,1.20:1, 1.00:1 R 2.20:1.
>From SN B-9470057 on up they used a Ford HEH-E or HEH-B.
HEH-E ratios: 2.32:1, 1.69:1, 1.29:1, 1.00:1 R 2.32:1.
HEH-B ratios: 2.78:1, 1.93:1, 1.36:1, 1:00:1 R 2.78:1.
The Ford HEH is the classic "Top Loader" that Ford Hot Rodders
talk about. The 5 or 6 bolt problem applies to the bell housing, not
to the transmission. My Tiger II came with the HEH-B and an aluminum
bell housing that fits with no modifications on a 289 and Boss 302. The bolt
holes lined up on my 351C; but the larger diameter flywheel rubbed the
inside of the aluminum housing so I switched to a steel bell housing off of
a Bronco.
There are many variations of Tigers; so what is observed on one may
not be true for all cases.
