What is this?? 318 stroker??

I would have to say it is also fake.....Different font on the engine cu in ....look at the flatness on the top of the number 3 compared to the other........and it also looks like the whole 3 digit area is raised higher than the rest ....Like another piece over the top....I would have to say probably as said earlier, someone was trying to "skirt" the racing rulebook....LOL
