Default 351 Cleveland Ignition wire diagram

Hello Group,
Ok I know its a truck but its powered by a 351 Cleveland motor
I have a few questions,
1. How can i tell the year of my 351C, and if its a Boss motor or not?
2.Need the spark plug wire diagram and firing order?
3. What spark plug is recommended for the 351C when running NOS?
You can see photos of my truck on the ZEX website at www.zex.com
click on the project cars and then click on my blue 72 F100.
Thanks and hope to hear from some of you soon.
PS if theis helps my Brother-in-Law has a 97 Cobra Mustang which he races along with me at Norwalk,Ohio.

Boss is solid lifter. No other 351C is. Read the casting number on the block above the starter. That'll tell you the year the cast was designed, at least. Actual engine date would need an external tag or identification of the internal parts. Low compression would make it '72 or later.
