M = Mexican casting. I see nothing for "9VP" or "VP". Could be a crate engine or a light truck engine. Truck suffix codes aren't that well represented in most data bases.

The block casting number would be a better indicator. The suffix you have is often seen on the c/n 10066036 block- which is a 1-piece rear main seal block w/o the casting bosses for a factory roller cam and lifters. Whether or not this relates to your engine remains to be seen.

To tell if it's a roller engine, you might be able to see down past the p-rod into the lifter valley if you have good lighting. If you see the roller cam spider, that tells you. Or you can remove a push rod to see if it's a roller or not. Flat tappet p-rod will be about 7.8", the roller engine uses a 7.2" p-rod.

Good luck.
