I once swapped a euro intake manifold into a 73 BMW which took a four barrell carb. The intake was used in Europe without a brake booster so there was interference. I eventually ground some material off the manifold corner and put three or four washers between the motor mount and the engine arm. That tilted the whole motor over a bit and gave enough clearance. You might be able to do something similar. I know you can do a remote filter but those always make me nervous.

Great idea!
