350 engine info

I recently picked up a 350 engine that was aftermarket install on a blazer. I have installed it in my 25 Dodge Coupe. Since this is all new to me, I need to know the best way to determine engine year, specs so I can get a manual. The number on the front of the block is V0416XJN. I may not know what I'm doing, but I sure am having fun!! Thanks to anyone who can help a hotrod newbie.
