I have recently picked up to FE Ford engines and I am having a very hard time figuring out what type of engines they acally are.

The casting number on the first engine are C7ME-A
According to
http://www.fordification.com/FEcasting-numbers.htm

330MD Medium Duty Truck engine or a '67-'70 428 c.i.d. 428-4V, Police Interceptor, Cobra Jet

The second engine says 8D30 20D11

Any help that any has a would greatly appreciate! I know nothing about Fords
