I have the Barton inline 2x4 intake with 1/2 shaved from the carb mount pad. Mine is in a Barracuda tho so clearance will be different. I have Schumacher mounts which raise engine 3/8 to 1/2 inch over stock. You don't have that issue since you used Hemi k-frame. I have the drop base bottom from FHO. All put together it was very, very close. I use little cigarette-size spikes made of modeling clay to check clearance at front, rear, each side and anywhere a piece of framing gets close. I have about 1/2 inch at the closest. Good thing the mounts won't let the engine move.
