Hello,

I'm restoring a 69 mustang with 5.8 351w 2v engine(at least, that's what it's supposed to be). there are a few parts clearly not original like a 4bbl carb, edelbrock intake and, I dont have much experience to see stuff like immediately, the rocker arms.
so I have a question:
I will post a a few pictures and can somebody say if the cam, cylinders, pistons and other stuff you might notice are original(or original spec, no aftermarket upgrades) on the engine.

(Small background) I know...

aftermarket parts?
