67 440 dart

That link may be to the mod. for the blower motor, but I think it only works on non-A/C cars.

On my '68 440 w/ A/C, I could fit the factory valve covers that had the indention (slope) by the blower motor. I had 2 pair but they were both in poor shape, so I ordered the cheapest chrome valve cover I could find and dimpled them with an air hammer. It's not that noticeable.

Note: I have Edelbrock RPM heads on mine, don't know if there's a height difference
