Look at these areas in the photo as reference to your engine and then do a google search. You’ll find everything you want to know about your engine.

None of your photos show the ID pad, the casting number, or the casting date of the block or the heads. Without that info, ID is not possible. Photos of your aftermarket water pump and your Edelbrock intake manifold are meaningless in identifying the engine block or heads.

There's no photo of your ID pad in the photos you posted - you have photos of your intake manifold, air cleaner, water pump, and valve covers, which provide no useful info. The ID pad is easily accessible on your engine since you have no air conditioning. Here is a photo of a Chevy ID pad - you can easily provide the same type of photo. Your casting numbers and casting dates are also easily accessible if you take the time to shoot them as Jeremy showed you above:

we do not recognize those numbers. look at pic lars posted. flat pad. directly in front of right head. and behind water pump. if nothing there at all, it has been decked. which means it has been rebuilt. which means whatever it left the factory as is moot. post a pic of the pad. your first pic shows some of the pad. i believe this is 77-later by the tiny bit of the pad i can see. it ends at the water pump bolt.
Lars' pic shows the earlier, wider pad which a 69 block would have had.

If the stamp pad has those numbers then contact the seller (I assume it was the dealer in New York who was selling it?) Ask what engine is in there, he just advertised it as a 350, and what has been done or ask that the previous owner contact you with the info he has... If the dealer has none, and unwilling to cooperate by contacting the previous owner, then there is no way to know much about what you have without some forensic work.

Perhaps it is listed here under the c3 registry which might provide some information? https://www.c3registry.com/index.php. Or google the vin #

Good luck.

From you description I expect you have a GM crate motor. If you measure dimensions of engine stamp pad I expect they are about 38mm by 25mm.

If you examine left rear (driver side) block, I think you will find "HECHO EN MEXICO" just above block's casting number.

Your "1M0425 and under it 30VP" stamp pad description is similar to stamp on a GM "Goodwrench" motor I have.

If so, these were supplied in a long block configuration as a general replacement 350 ci engine.

Web search for "GM Goodwrench" will supply additional information, as well as numerous threads of folks horsepower modifications

i have a 502 GM engine. has a plate riveted on says GM. 502, 461 hp. not for marine use. plate is down low on the front near where fuel pump goes. if you find nothing like this, get a borescope off amazon. go in through the spark plug and you can see if dished or flat pistons. pull valve covers for head casting numbers. while valve covers off hold a steel ruker next to valves and crank over to get an idea of valve lift. 4-1/2 inches is mild. over a half inch is aftermarket.you could get a timing tape and dial indicator and balancer degree tape and degree cam in place. now that you have a borescope you can tell your wife you can do cervical exams for all her girlfriends. and her sister...

I see lots of aftermarket bolt ons and I can tell its a small block chevy but without the numbers stamped on the engine block that all I can tell... and even with those numbers, you cant tell if its a 355 ,383 or whats been done to the block if rebuilt which is likely if its a crate motor. The numbers on my block for example say its a 1976 4 bolt 350 from a c20 truck... They dont reflect the fact that its been rebuilt with flat top pistons, a performance roller cam and 64cc heads... just saying.
