I have a Clifford manifold and adaptor on my 261 ci. I just change from a Carter AFB to one of Tom Lowe's 600 Holley 3 barrals. The Carter sat on the manifold side ways. So, I decide when I put the Holley on I wanted it to face the correct way. I had to hogged out the bolt holes on the adaptor to get it to work. Because, I didn't have the proper equipment to do it right it was a pain. But, I got it to work with no leaks. And I like the look with the carb sitting the way it should. For a street cruiser it works great.
