C4 versus FMX

Can anybody tell me the real difference between the C4 and the FMX. Just give me a link to go to if possible.

C4 is all aluminum and very small.

FMX has a cast iron case, aluminum bell and extension housing and weighs about twice as much as a C4.

FMX is a way stronger tranny. It will take horsepower & torque of the Big Blocks. They used them behind the FEs, 390.
