Couldn't find that number at Mortec, but 3951509 is a 400. hth

350 cu/in block used in GM Goodwrench Crate Motor. Made in Mexico.
I'm not sure the exact year of the engine, but I just found an engine with the same casting number and due to the offset engine mounts I believe this to be a Chevy 292.
