The 200 showed up around 1960, but 1966 was the 1st year for the 6 bolt bell housing and it remained in the same configuration through the end of its production around 1980. A 1976 engine would have more emissions controls than a 1966, including an EGR valve. If that engine doesn't have an EGR I would be inclined to say it is a 1966. At least the head anyway. In the 50 year life of an old car, no telling what was all swapped around on it.
Please look at the picture. It appears my exhaust manifold is attached to the bosses on the head! I must have the wrong exhaust manifold for this year. Are there different exhaust manifolds? If so I need to find one and change it out and problem solved. Please let me know. Thanks
No - yours is the way they all are. The intake is on the top and the exhaust is part of the bottom. Look again at the last picture I posted. Of course the head is upside down in the picture. You can see the 4 single exhaust ports for cylinder 1, 2, 5, & 6 - and the center square is a dual / combined exhaust port for cylinder 3 & 4. Your head is set up the same way. Notice how the valves are switched around for that combined exhaust port. I found a pic of a 65 head and it did not have the 2 holes you are looking for. So I'm going back to my theory that not all heads have them. And I'm like 99% sure you have a 1966 head. I numbered the exhaust locations As you can see the 2 bolt holes are between cylinder 5 and 6
You are correct it must be a 66 head. There are no bosses there. I can see and feel that area clearly. Your guidance and pics really made it clear. I need to design some sort of bracket to make it work cleanly. I hate the thought of switching the head just to have a proper mount for the throttle linkage. Again thanks so much!
Can you post a pic of your carburetor on the linkage side? I can tell you which cable setup you need once I see the throttle linkage on the carb. Probably as simple as getting the Falcon style bracket.
That pics helps a lot - the carb you have there is wrong for that 1970 linkage. I'll explain. Here is a picture of the 3 linkage set up on the carbs. Left to right number them A-B-C A - has a lower linkage mount to use the leverage from the 1970 style which causes the throttle to push up on the carb, This carb linkage moves up and down. C - has a higher mount and is designed for the linkage to pull across the engine, right to left on the throttle linkage. B - is a combination of the 2 so it could be connected on either style linkage To make your carb work, you just need to find the linkage that uses the bracket that bolts across the engine and pulls right to left. Not the 1970 style you are trying to hook up.
Here is a pic of the style throttle that works with that carb. The bracket is the key here as it makes the cable pull right to left.
