Hi Scott

I know what 60 th over is but what are Aussie heads

John,

Here ya go - another cut & paste from Wikipedia:

302 Cleveland

Note that there was also a 302 "Windsor"

This engine was built only in Australia from 1972 to 1982, and was intended to give their consumers a smaller capacity alternative to the Geelong built 351 Cleveland, as Ford Australia inherited the patterns, molds and tooling for the 'Cleveland' it was a viable alternative to importing the 302 Windsor. Using a locally reproduced 351 Cleveland block (1972-1985), 302 cu in (4.9 L) was attained by reducing the stroke of the 351C from 3.5 to 3.0 inches (89 to 76 mm) and increasing the connecting rod length from 5.780" to 6.030". Additionally, the 302C cylinder heads were redesigned locally, with smaller combustion chamber(from 72cc to 58cc), to compensate for the reduced stroke of the engine.

The combination of closed combustion chambered quench heads with smaller 2 barrel style ports made a more powerful setup known in the USA as "Australian Cleveland heads". These heads interchange directly onto 351C engines, and are somewhat sought after outside of Australia as a low-cost method to increase compression ratio. They are a good street alternative to the over ported 4 barrel heads. Using the 302C cylinder heads on an otherwise unmodified 351C may increase the compression ratio beyond a safe level for regular pump fuel. Using the small chamber 302C cylinder heads properly requires engine design checks (deck clearance, piston design, camshaft specifications), all optimized for the intended use.

Even though the 302C was not made in Cleveland Ohio, (but in Geelong, Victoria. Australia) the engine has been affectionately referred to as the 302C. Ford engine suffixes are confusing enough, to say the least, so to keep it simple call it what it looks like: a Cleveland. The last 302C was installed into an Ford XE Falcon Fairmont Ghia ESP Vehicle Identification Number JG32AR33633K in November 1982.

Hope this helps- Ray

RayThanks for that

of course I knew abut the 302s being built in Geelong

they still build engines there

the 4 litre twin overhead cam L6 ( refered to as the second best L6 in the world) after the 3 litre BMW

I was never aware that Geelong heads were

refered to as Aussie heads

also back in the 70s here a 351 with 302 heads made in Cleveland

were refered to as "Boss Motors" or maybe the heads were Geelong heads

not sure wether it was an official name or not

we still get V8s here after a 10 year break which gave the oposition

GM Holden a big advantage as well as a whole generation

of drivers that didnt I should say couldnt buy a Ford V8

and are Ford paying for it now

anyway from 92 we got the Canadian 5 Litre V8

then the 5.4 litre 3 and 4 valve V8 and now the 5 litre S/C V8

so theres a bit of info back to you

John
