my 1980 olds originally had a 307 put in but the privious owner put in a 350 olds everything is ok but the vacume lines are missing and some of the vacume switches are not looking like the diagram for any 1980 engines i have seen. where do i find out the year and system i have i tried looking up the number that is cast on the intake but i haven't found any for olds are they the same for chev?

It is probably a #16 iron intake. What number heads are on the motor? Is it the original computer controlled carb and distributor?
the dist has the extra terminal for the timing advance and a non computer controlled carb. the intake looks aluminum the extra terminal goes to a vacume sensor that adjusts the timing

that's what i am thinking. i am thinking of pulling the dist so i can see the numbers at the rear of the engine.
What number heads do you have? That tells a lot about the engine considering it's not a mismatched motor. (Example: 75 block, 70 heads, and 77 intake.)
