I have an engine I'm trying to rebuild/build-up for my 79 Styleside F-150 mudder. I got the engine from a friend who got it in a racecar he bought. He knew squat about the engine and said they told him it was a 400. I'm trying to find out the specs on it (year and size) but I can't find the casting codes. WHERE THE HECK ARE THEY?!?!?!?!
