Well the intake is a '79, off a Granada Enginge. For the block I do not know without its casting number which is at the back of the right cylinder bank. The transmission is a '66 Full Size Ford. I am not sure what p is for but i would guess its the code for transmission. The 7D027 is a date code for when it was cast.
If you get the engine cast number that will tell you more because the intake could of come from a different engine.
I hope this helps some.
