I have a Montanieer truck that stole me and I already found it but they spoiled my engine, at the bottom of the block there is a hole, it seems that the piston came out. This engine is a V8 5.0 1997.
I have an engine of a 1989 V8 5.0 Crown Victoria too.
The question is, the 1989 motor block will stay at 1997?
You would have to disassemble the two and check them physically on the other hand, it is still almost the same with some variations and perhaps echo you would have to grab the original engine some exterior parts.
