Engine info…

So the story goes like this: the 350 is the original engine out of the family 72 turbo 350 auto , grandpa got passed by he friend in another 72 manual on their way camping, so my dad and uncle ( both have now passed) fresh out of auto tech school at ISU and the friend went to play on vacation for a week, they bought 3 396’s and put together a nasty 404 …. But ol yeller is numbers matching, but i have the engine after the 283 puked.. I remember as a kid watching my dad put it in, it was his daily after all. His life blood at the time.
