Ford 302 engine - $1 (Hampton va)

Selling this 1991 f150 5.
0 302 engine it is in good condition however the spark timing is not the same as what my ecm is set up for and the injection is being told to fire on the old engine order “if that makes sense “ it’s just not compatible with my 96 bronco .
.
this engine runs no smoke no issues and is made for 1991 and earlier EFi vehicles for ford truck and vans and probably mustangs as well .
.
I’m open to offers or trades
