RIP 340 Onto Magnum swap

Lots of thought and patience. And a good set of gloves! When I removed a 318 from a 77 van, I took it out from where the doghouse cover would go but I was scrapping the van anyways so I could afford to be clumsy (and at 21 years I was!). Having a sawzall at hand helps! (I didn't have one though).
