Obviously there will be a block off plate to left of the distributor. If there isnt a plate, more then likely you have a common block.Ya, the lack of the fuel pump block off plate to the left of the distributor is usually the first sign that it's a common block. Once you have access to the rear of the engine you can see the year cast into it.
ya u said it allmy 89 common block has a 88 year make ,so be %100 sure and not %99
What is the date mark before 88?,for instance my 8-10-88 it will be a 89 block.
Not sure exactly what month the manufacturer began the 89 block,I will place a guess it will be beginning in mid July (7).
Maybe someone can confirm or dispute that month.
Also, I didn't see you confirm the block off plate which really tells the story.
Here is a early 2.2,as you can see the fuel pump is to the left and slightly under oil filter,now imagine your going to block that off.
If there is a physical plate there its a non com.
Now,If its a com block,there will be no way a fuel pump could be located there,or any place to bolt a pump at that location,it will have a slight "horizontal running" rounding of the block here.
check again, be %100
Sounds like you have a N/A engine.The last 2 digits on the back tell the year....generally 89+ is common block, no fuel pump plate, straight rear oil pan rail and thicker mains and more casting in the bottom end. But beware....there are "common blocks" that appear to be T1's. I have one. They come with T1 rods and stuff but the block itself is just as strong as the common block.
