He misses the turbo. Where's Garry the Snail?
The funny part is that Ford USA directly managed Ford Austalia, and though its true that it used a large percentage of cast off parts with previous years emissions standards in lag, it also spit polished a lot of logs. I think the automatic 250 for 1979, even with a cross flow head and a single 1-bbl Bendix Stromberg Technico carb passed US 1973 emissions and made an exactly 46% loss at the rear wheeels. A not uncommon Horsepower loss for an auto in line six.
Thats where the the rear wheel horspower can double, triple or quadruple on any domestic US or Australian I-6.
63 REAR WHEEL HP TIMES 4 IS 252 rwhp horsepower. CMA could have quadrupled his log head 250 Maverick engines rear wheel horsepower!

On Page 35, the Falcon, Commodore and Holden Kingswood were retested, the same models but the Falcon was an XD this time. The variance was interesting, with the Falcon six worse performance wise than the 330 pound XC tested in March 1979.
It's interesting to note the differences.
The Falcon XC 4.1, in good tune, gave 18.6 sec 1/4 mile
