 Are you kidding?  Very, very few Americans even know of the existence
of the 302C.  Anything from Australia might as well be from Mars.

 Yes, the 351C block is a little heavier, but it's within five pounds of
the Generic Motors Chevrolet, and the longer rods and bigger bearings
are well worth it.


-> the same - makes life hard when you need to tell at a glance what the
-> capacity is. Trust me on this, but the 302 loves to rev its head off,

 Is there any difference on the crank flange at the flywheel?  How about
the harmonic balancer?  Not that you can see either very well while the
engine is in the car.


-> Anyway, I have a query. I have been told that the 351 motors produced
-> here were more 4 bolt mains than 2 bolt mains. From about 1975 on, we
-> produced 2 bolt only and imported the 4V 4 bolt mains 11:1 motor from
-> the US. What was this motor, was it a 351C?

 According to my Ford stuff, all US 351Cs were cast in Cleveland, Ohio.
For a few years, they were shipped to Ford Australia for machining, then
shipped back to the USA.  Wierd.  Anyway, Ford USA canned the motor in
1974 after a five year production run.  Your post-'75 US four bolts were
probably shipped out of existing inventory.

 You might be interested to know that Ford's Muscle Parts and
Off-Highway Operations in the early '70s sold Aussie four bolt blocks at
super-premium prices - close to the cost of a complete US motor, just
for the block!  The Aussie blocks were a better grade of cast iron, and
were thicker wall construction, probably because Australians didn't see
any point trying to cast sheet metal.  The US 351Cs had some flimsy
areas... like the cylinder walls.  <sigh>

 The early Falcons used 351 Windsor motors, but I have no certain
information as to where they're from.  I tend to think they were
imported from the US, since Ford Oz was so proud of their 351C.

 Incidentally, the 351W came out in late 1968 here in the US.  The BOSS
302 and 351C came out in '69.  The Ford information I have indicates the
BOSS 302 was designed by Ford for Trans Am racing, and the heads were
adapted to the Mercury-designed 351 Cleveland.  I've never been sure
exactly *why* Mercury wanted their own motor, or why they disowned it so
rapidly.  It would have been much more reasonable to put the BOSS heads
on the 351W, like the common B&A conversion here.  Ah, well...


-> produced 2 bolt only and imported the 4V 4 bolt mains 11:1 motor from
-> the US. What was this motor, was it a 351C?

 Four bolt, four barrel 11:1, hydraulic lifter - that's the 1969-1970
standard 4V motor.  For solid lifter, it'd be the BOSS 351.  For solid
lifter, 8:1 compression, it'd be the 351 HO.  Both were made only one
year, available in the Mustang only, and are rather rare.


-> lbs (1568 Kg), hey? Boy those were the days. Now we get this 5.0L
-> Windsor (made in Mexico?) and fair dinkum, it would have trouble

 I've heard the Mexico rumor before, but nothing to authenticate it.
I'd kind of like to know if it's true, because the Mexican Chevys are
nothing you'd want to trust.  Up here, people think a "5.0" is a monster
motor.  <sigh>  We all know, of course, you must have at least seven
liters to pound your chest and rattle your cage... but compared to a
1600, I guess a 5.0 does look impressive.
