Oh, you are correct. Oh well, 470 cubes can't be bad!
I'm working on some pen drawings of the various breeds of the XK2000 family tree. It starts at the little 144, then goes 170, 200, 188, 221, 250, 3.9 liter and 4.0 liter OHC's. The 4.0 DOHC Falcon engine is being made in Australia with over 320 bhp. The front drive Topaz/Tempo and early Taurus cars used four cylinder versions of these from 1984 to 1995, 2.3 and 2.5 liter ohv engines called the HSC.
There are lots of changes because a six cylinder engine can easily have the crankcase width altered, the cam position raised, the width of the block modified, and the amount of space varies with block height.
There are five deck heights in inches (1"= 25.4 mm). All have similar 30.3" (770 mm) bellhousing to front water pump pully.
Type 1. XK 2000 Falcon
7.808"= 144, 170, 200, US from 1960 to 1984 (200 from 63-84).RHS High mount starter until C5 transmission in 1980. Seven main bearings after mid 1964 on 200's. 170 had Seven main bearings after 1970. Bell patterns were 132 tooth flywheel till 1965, and then got bigger flywheels with 134 teeth in 1968, then 148 on some. Last Big Bell in 1980 was 157 teeth. 2.75" x 6 bolt crank .
Type 2. XR 66/ Argie
8.425"= 188, 221, Made only in Argentina from 68 to 95, Australia from 1968 to 1971. RHS High mount starter. Seven main bearings. 160 teeth, bell pattern different from US as it allowed 9.5" bellhousing. 2.75" X 6 bolt crank flange with 4 bolt bellhousing similar, but not the same as the US 1968 blocks. Had sought after Maxi Eccono (ME), Super Performance (SP), or plain Log heads.
Type 3. US 69er 250
9.469"= 250/4.1 Log American I6, 1969 to 1979.RHS low mount starter. Real tough specially enlarged front crank snout, with special gears and cahin, and cam spaced far above crank counter weights. 6-bolt US Small Block V8 bellhousing with the bigger 3" x 6 bolt crank flange
Type 4. XY 71
9.380"= 200/250 (3.3/4.1) Log, 2V, Crossflow Australian engines from 1971 to 1993. Similar to US 250, but with less deck height, low mount cam and RHS high mount starter.Crank snout same size as XK 2000, so much smaller than the front of a US 69 250 crank. Cam not as high in the block as the US 250. About 9.5" wide at the crankcase, about an inch narrower than the US 250. 4-bolt Australian XR66 bellhousing but with the bigger 3" x 6 bolt crank flange. This makes 1966 to 1993 Falcon OHV engines the same at the back.
Type 5 FWD I4.
8.630"= 2.3HSC I4-cyl. Five main bearings. Designed for Mazda transaxle.
Type 6 FWD I4.
9.380"= 2.5 HSC American non-crossflow I4 engines from 1986 to 1995. Designed for Mazda transaxle.
Type 7 EA26 OHC.
9.220"= 3.2/3.9 OHC and 4.0 OHC/DOHC, LHS high mount starter. Seven main bearings. Odd ball metric crank bolts but 3"x 6 flange, with 5 bolt bellhousing. Unlike any other block. Cranks varied from 10 couter weight to 12 counter weight versions, later DOHC variants were not interchangable, while bearing diameter and rod length increased in 1998.
Widths vary from engine mount to engine mount is about 9", but the US250 engines are about 10.5" from mount to mount. The sumps vary, with about 9 types.They are not interchangable between types. Dipstick positons vary on Cortina Sixes (Taunus), and the non-cross flow blocks are 5.59" wide at the head gasket, but about 7" wide with the Crossflow or OHC engines.
Someone like the Schendahl brotthers can fill you in on the valve sizes for the sixes. There are some very big valves on the later American engines after 1974.
And it will fit perfectly!
