A 76 should be pretty basic there may be a sticker under the hood , a large one for the PCV valve . a smaller one for the vacuum advance , and the tranny module is off the manifold , Got an ICP thing gong on ?

Sadly there was a engine swap from the 250 to a 350 with a rochester dueljet 210 carb now

Im working with those fitting nothing was connected when I ended up getting it
