I need to find the year of my motor. Its a chevy 350 crate. (Casting # 10066036) Then next to the casting number it says (95) (Sufix code # 1m1017) then under the sufix code it says (6vp). Ive tried everything to find the year of this motor and no luck, so if you have any information it would be awesome! THANKS

So, here's the short story on your engine, by the casting number, 10066036;
"10066036 - 1986-up 350 Car & Truck 2 & 4-bolt Passenger stick 1-piece seal"
This engine block was probably cast in Mexico, that became popular in the early, mid-'80's as a cost cutter for the big three.
It would take a deeper probe to find out the original exact horse power and such, but before all that digging, I'd check the head, intake and exhaust casting numbers to be sure they are are all 'like' components.
This engine probably came out of another vehicle, rather than a crate, and could at some time in it's prior life had the heads and other stuff swapped around.
It's probably a 250 hp (when new) engine, that was the most common version of this casting.
Good luck with your project!
