Gee Rich, here in Oz it means the same thing..

Yup same here in OZ

OK not quite of the 6cyl hemi, but still very central.

You must have had some real interesting slant 6's at you high school, coz
the 6cyl hemi heads I know are a lot different from the slant 6's
> That Valiant is NOT a true Hemi head...
How so, it forms 1/2 of a sphere (well OK the flat valves put some dents
in it but other than that 1/2 sphere)
> My car is, some Toyota's have been but I can't remember which model,
> but NOT slant 6's...
Agreed not slant 6's but we are talking about the OZ developed HEMI 6cyl
not the old slant 6

Well someone forgot to tell the designers coz thats what they have...
> Hemi heads Flow better than any other design.
Yup thats why they got 300+ HP from a factory 265 CI 6 cylinder....
Rich just because its not 'mericun doent mean its no good.
the Hemi series of 6's were great motors, strong, reliable, tolerant of
obscene abuse, developed good power, even better torque and were capable
of excellent economy (particularly in the later ELB guises) That chrysler
US didnt make use of these excellent engines, even though the initial
design was started in the US in 1966, says a lot about chrysler
