engine identification

[white horse]

I just purchased a 1986 4 square headlight, hatch. The emission sticker under the hood shows the car was a V-6 3.8 from the factory. It now has a V-8 five spd. How can I identify what cu. in. and what year block was installed?

this is a link to where the casting number should be found http://www.aacncclub.com/FORD_BLOCK_CASTING.html  289-302 intake will not work on 351 so maybe you could find out what intake you have to tell if its a 302 or 351 or something else
