Would the circle bolt pattern on a transmission from a 223ci hook up to a 302 or 351W?? If not, what other engines would it hook up to if its even possible??
You do not say what your transmission is or the year of your truck. IF it is a 4-speed (T-98), it will be the same through all the 223 years and will fit at least some of the bellhousings that will fit the 302 engine. If it is a three-speed, it is probably the narrow Ford pattern and will not fit most 302 bellhousings (there may be a exceptions).
Give us a few facts & you will get a better answer. There are more issues to deal with because 223 truck bellhousing had motormounts on them while 302's had their rear mount on the transmission. This can be dealt with, but it is not as simple as a straight bolt-in.
P.S.: Bellhousing to engine bolt patterns are not the same.
Well Im not the one that has the truck, its my buddy that has it so I dont know the transmission yet as of now. I will have to get back to this at a later part of the weekend possibly monday.

No. the pre-65 and 65-up transmissions have a different pattern where they bolt to the bellhousing. Use the bellhousing for the engine you have. Transdapt sells a plate to convert old/new ford transmissions to old/new ford bellhousing. If its on a 223 its a pre-65 trans to bell pattern transmission.

Kalashtar: I have seen 302 bellhousings with both narrow and wide patterns, but I could not tell you what years they came in.
One good point about the Transdapt adaptor plate is that the clutch linkage can be left as it is. Using this adaptor put a 302 block against a 223 bellhousing is a simple solution, but you will still have to arrange for engine motor mounts. There are cross-member kits that bolt or weld in to solve this problem. This will give you four motor mounts, but that will be fine so long as you make sure that each is getting its share of the load.
If you want to put in an automatic or late transmission at some later date, you will have to scrap everything from the 302 back (including the adaptor), and put in a cross-member to support the trans mount. I am mentioning this to get you to plan ahead before you buy the adaptor. If you will eventually want engine & trans to be late-model, it would be cheaper to do it all at once. If you can buy an engine & trans all together, you will save the cost of the adaptor. Be sure to get the rear transmission mount cross-member if the engine/trans is from a truck. This is a case where buying a donor truck can be a good way to go.
T-88?? I know T-98, T-18, & T-19. Somebody tell me what a T-88 is.
If you have a common light-truck 4-speed, I believe that bolt pattern was carried forward into the years when they started putting 302's into Ford pickups. I do not think there ever was a Ford 302 in a truck with bellhousing motor mounts, so you would have to decide on how to deal with the motor mount situation.
Let me summarize the motor mounts used in Ford pickups:
Up through '64, there were two motor mounts (left & right) that connected two "ears" on the bellhousing with a cross-member that went under the bellhousing. At the front of the engine, there was a single motor mount. (On your '63 223, this mount was way far forward because of the length of the 6-cylinder engine.)
From '65 & later, Ford used "passenger-style" motor mounts on the pickups up through 'F-350. This involves a left & right motor mount around the middle of the sides of the engine, connecting to a cross-member that goes under the engine. At the rear, behind the main case of the transmission, there is a single motor mount that has its own cross-member.
I am in the process of putting a '67 240 I-6 and its trans in place of my '61's 223 & T-98. I am changing from the first system above to the second. I am using the rear mount cross-member from the '67 - this is easy because it bolts onto the bottom flange of the frame with two bolts. I a going to fabricate the front cross-member, but this is an item you can buy from the aftermarket. There should be plenty of threads about this one these forums. You also need to make certain that the rod going to the clutch throw-out fork is horizontal after you put in a different bellhousing - again this problem has been dealt with in these forums.
