Intake suggestions for a 440 66 dart

Sounds like you'll need to use a low profile intake. Perhaps a Performer intake or maybe even a factory cast iron unit. You might be able to find an old factory aluminum dual plane (made by Edelbrock). They show up at swap meets sometimes.

If you put cast iron manifolds on it then you'll want to stick with a fairly mild camshaft, especially with a stock type dual plane intake.
