The clearance is more of an issue on my 69 than on the 63, but it's not a big deal by any means. I didn't like the low profile filter Langdon had, so I went with the K&N 56-1020. The included velocity stack fits on the 63, but I had to leave that part off on the 69 for the filter to clear the hood. That's the only clearance issue I ran into.Originally Posted by NovaJoe99
i am thinking of swapping my one barrel for the two barrel progressive with adapter from langdons,after talking with him,he made it sound like a challenge with the adapter + carb height not hitting the hood,and i would need a low clearance air cleaner.he could not help me with a linkage kit either.does this type of set up work for most people?
