bottom 1 looks kinda like Ford??

 OK heres my guesses,

 First pic,  left to right, BBF rear plate, BBF front cast mount, flywheel cover (see what the bolt holes line up with), and what looks like an attempt to make a front mount for a BBF that replaces the water pump blockoff plate (not sure what that round hole is for)

 Second pic, left to right, BBC front plate, BBC rear cast mount, BBC front cast mount.

Thanks everyone... im a bit confused on your answers.. so do I have them all mixed up? Hahahah .. what I need is to separate them so I know what goes with what ...  and I need the set for a bbc and gonna sell the  other set if I can ...  should. I line them up and put numbers by them and then you guys can tell me what numbers go together  to make up sets ...   thanks again...

1st pic, 2nd from left, BBF front mount. Youll need these to attach to stringers. Dosent look like you have the matching rear mount.

Do I have what I need to run a 454 bbc .. other then buying the mount feet I need do I have the plates I need?  Thanks ...

 Yes
 Second pic. Center one is your rear mount and the one on the right is its matching front mount.  You just need the proper mounting feet for them.
