Most stupid design blunders were in a Plymouth Fury I with a
blueprinted 440 cubic inch engine (7.5 litres to you) -- back 2 plugs on
the nearside bank officially couldn't be changed without removing the
steering column. And the engine weighed so much the front brake disks
warped repeatedly. Left that car parked for a while and it sank
through the asphalt driveway -- it weighed over two tons.

Two tons isn't *that* much for a big car. In fact a Defender 110 is
about three tons...


I know -- I have a 110 Station Wagon. And one of my sons has another.
However we're talking about point loading here and if you look at the
way the engine's mounted in a 110, it's a long way back. Fit an
electric fan to a 2.5 litre model and remove the viscous fan and shroud
and there's almost space to stand between the radiator and the engine
:-). The V8s are light alloy blocks. That 440 was a lump of cast iron
which entirely filled the massive engine bay and a large proportion of
the weight of the car was actually on the front wheels. And the
driveway was a North American effort which amounted to just a few inches
of asphalt laid on the ground without any hardcore or anything
underneath :-(
