being from fordsix.com/forums... it looks like you have a 200ci!!! woot, a stroked 170
the good, 30 extra cubes, you also have a larger log head giving more air and power, and instead of 4 main bearings it has 7 main bearings, making a smoother and better power curve (so says ford documentation)
the ignition looks like a 74-8? DSII, it's the best IMO, the radiator is just a simple replacement, probably a 3 core, originally a 2 core.
it looks like they kept the 170 exhaust manifold, also carb hat, but that carb looks like a carter YF, not the autolite 1100 it should have, but that's expected as the carb bore changed from 1.5 inch to 1.75 in 69
the great news, is that your 200 fits EXACTLY the same way as the 170. everything is the same, except the height of course. so if you really wanted to go 170, it will bolt in place even to the trans it's using, BUT the flywheel will be different. the 170 uses a recessed 8.5 inch clutch, the 200 can use it but it's common to go the standard flat 9 inch clutch. so you won't know until you tear into it. but it will use the same starter, belhousing, trans...
I will check my 66 doors and see if there is a key hole on the pass side.... I honestly think they just used a later handle on the door as it's cheaper than the 66 handle.
EDIT: taking a 2nd look at the engine, try and count how many freeze plugs you got on the passenger side... 3 = 170ci 5 = 200ci
It's possible they just swapped the head over and grabbed all the other good stuff to help improve hp and mileage
