Say Why Blower Manifold??

In 1971, I found one on a 413 at a local salvage yard. It had a 671 blower set up with a chain drive (maybe motorcycle chain) and 2 carb adapter plates. I bought it cheap thinking about putting it on my 68 Charger R/T. Lol. I was 16 years old. What did I know. My car had A/C so I knew that would have to go. Then I realized the windshield wiper motor would have to go also. And then the hood would have to be cut. Finally I read that the pistons needed to be low compression. Thankfully, I came to my senses be ever starting on it.
