Like the title states. I may have a 9 motor in an 85 Delta here. Not that it's a bad thing, but how do you find out?

I know the block ID is going to be the same, so I'm going to try looking at the VIN plate on the side of the block. What would I be looking for on there?

 

Should be simple, if the engine is an original '85 and has not been modified. In 1985 the 9-code engines still had 5a heads while the Y-code engines moved on to the 7a heads. there are other differences, but that's the easiest to see.

 

If it's the original motor, this is easy. It's not a "9".

If it's not the original engine, the VIN derivative won't tell you anything as it does not contain the engine code.

 

It's not the orginal motor, I was told it was replaced. The AIR tubes are NOT rusty and crappy looking which I was surpirsed to see.

The battery ground is right above the head ID. I can see the "A" but not the number
