Vin Number Confusing

[Brett_s]

So im in the process of digging out my girlfriends dads old grand prix. I went and got the vin from it and here it is. Everything makes sense except the engine code. If anyone can decode it and figure out what the engine code is that be great. I see the J as the engine code but it doesnt exist. thanks
