NB// and not directed to anyone, just CFYI.
The tech article on X-flows and Aussie non cross flow and 2v engines has been wrong since 2002, and hasn't been ammended. 221 Rod sizes listed incorrectly and dates of the alloy head (October 1980, not 1978), 2-bbl carb Alloy Head II (1982, not 1978).
There was a link to the ARDIE 221 crank formed by adminstrator Bedtime back in December 2002, but its long since gone. It was from a 1988 Aussie Streetmachine article. Last block I raided was in 1997 off an XT Falcon, so I don't have any pictures sorry. Asside from its wide block and extra 622 thou height, you can't pick it over a seven bearing 200 appart form its wow man red rocker cover and red block paint. It was rated at 135 hp gross, had the Dodge truck Stromberg 1-bbl carb like all Aussie sixes before mid 1976.
The Aussie 188/221/250 cam chain is the stock 200 timing chain, plus one link = 26 links instead of 25.
The extra link out places the camshaft further out, ultimately able to accept a 3.91" stroke with 2.124" crank jounal and so the Aussie 221 and 250 are the same regards cam placement, just like the 2.3 and 2.5 HSC Fours. The cam got relief cuts with the 200 in 1963, and cam to rod clearance is the same with the 250 as it is with the 200...marginal.
Details.
The 1964 XM and 1965 XP Falcons were XK 2000 based, but the Geelong build engines had the Aussies rolling out wide block variants with a variant of the 221 V8 (260/289 five bolt block 160 teeth) flywheels used for 9.25" cluthches to fix the massive waranty claims Ford Australia suffered with the 136 teeth 8.5" flywheel, a design which couldn't cope with the bulldust and heat of the outback without slipping.
These Geelong built wide block small sixes were seven bearing 200 Ford based, but lots more things were changed when the 188, 221 and Aussie 250 came out!
The Aussie and Argie 188/221 block were called 3.1 and 3.6 litre engines in funny English in when released in the 1968 XT Falcon sedan, utlity and wagon, and also the Aussie small Falcon wheel arched Fairlane but the engines only lasted for 2.5 years untill the 200 and 250 cid 1971 XY Falcon came out . The 1969 XW Falcon/Fairmont/Futura and Fairlane got it too. The two 188 and 221 engines were essentially duplicated in Australia and Argentina, but the engine survived untill 1995 in South America.
Detail changes for instance. The sump grew in width to about 1/8" to 9.25" and the block deck height for the 188 and 221 is 8.425", 622 thou taller . Rods were about 5.38" for 2.94" stroke engine, which used the small seven main bearing seven bearing 170 crankshaft which Dearborn designed in 1961. The 221 had a 3.46" stroke and 5.14" rods, used in Argentina too. Rods were forged steel.
The 1971 Aussie 250 revision was three years later than the US Falcon Pickup 250 commerical engine which was listed in 1968, (October 1967, really). The US 250 got a really big front crank snout, was 89 thou taller than the Aussie engine, an inch wider than the Aussie 250 at the sump and engine mounts, had the SBF flange pattern. Both Aussie 250 and US 250 got bigger mains, 5.88" rods. The Aussie engine had the same deck height as the 1986 Ford Taurus base model 2500 cc HSC engine, 9.38", the US engine 9.469". The 1982 2300 and 1986 2500 HSC used differient block heights, but the cam chain was US 250 based. Dearborn was first to upgrade the bearing sizes and crank snout, and it must have been done for solid reasons, and it continured in the HSC fours till 1994. The Aussie 250 based engines still use the smaller 200 Ford sized crank snouts, which remains to this day with all the OHC engines.

Ford crank in a GM motor, would never have though that would happen
