What changes were made on the engines between 64.5-67. are all parts interchangable ?
Howdy Steve:
Differences between a '64 1/2 and a '67 engines, assuming the same displacement and transmissions, were, for all practical purposes, the same. Some very early '64 1/2 engines with block casting #C4DE will have the 4 main bearing bottom end. Casting #C5DE and later will be 7 mains.
Changes in carb and distributor came in '68. Smaller venturi in the Autolite 1100 - not good. Centrifugal advance was added to the point type distributor - good! PS- this happened to Calif Emmissions cars in '66 & '67.
Adios, David

64.5-65 used a 6 bolt bellhousing. 66 and up uses the same 8 bolt V8 bellhousing pattern. Very importany if you want to put a T5 behind it

thanks i was just offered an old I6 out of 66 mustang for free and i was wondering how much of it i can uses but it sounds like almost everything
Not quite, Travis. There are four bolt patterns found on the 200/250 sixes. Small, Medium, SBF, and Big Bell.
Early engines had the "small" four bolt pattern.
Starting with the C6DE casting, there were two extra bolt holes tapped into the block to make it possible to mount the "medium" bronco/Fairlane 3.03 bell housing. That gives it six mounting holes, but only 4 are used on any application.
The C4 and 2.77 manual bell continue to use the "small" circle; the 3.03 style used the bigger pattern with the upper holes. Late in the 66 model year Ford switched all 200 sixes over to the 3.03 pattern using the "medium" pattern.
In 1969 the 250 was introduced with the same SBF bellhousing pattern as the small block 302. That was the only pattern available on that block.
In 1981, Ford introduced the E1BB "big bell" 200. This pattern is 2/3 rd's of the small block Ford pattern. The lower four bolts and the locating dowels are the same, as is the low starter location. The upper two bolts are in a unique location, however. AOD's and T5 bells can be adapted to this block by drilling two additional bellhousing holes. Not all bells are shaped to do this, however.
The big bell and the small bell blocks ran concurrently from 1981 to 1983 depending on application. A high mount starter is a small bell 200.

Hey, do you have any rough PCD's for those uper hole bolts on the post 68's bolts, Jack?.
On my last two links, I gave out the Aussie specs for bolt spacings.
http://fordsix.com/forum/viewtopic.php?t=4114 for 1970 to 1991. The four bolt spacings for these were pitched at 7.625 inches. I don't know what it was on the US ones, nor exactly what the Aussie ones were from 1961 until the last 221 six.(1970 ish)

I'd love to prepare a sticky for ya if there is any benefit. It's been many months since I've had a pre 1970 Aussie six, and I'm interested in if these have any common stuff to them for there four bolt bell housings.
If any one want's blueprint dimensions to use a proper US trans behind an imported Ozzy block, FordSix.com should be the first port of call.
I've got some of the XYZ co-ords of the post 1970 Aussie bellhousings, flywheels, flexplates and crank bolts, along with setback and teeth arrangements. I've made two adaptors my self, but I aren't into exporting anything.
