What does anyone think of these intakes?

Put one of these on the son's 70 Duster project on a 318 with magnum heads. The fit was good, the only issue is the holes for the vertical magnum are drilled for 3/8" instead of 5/16" so before you torque things down make sure it's aligned since you can easily be off.

Still waiting to get the exhaust system on the Duster, so don't know how well they perform, but I imagine it will be close to a true Edelbrock.
