Heat a gas grill or prepare a charcoal grill with hot coals.
Combine the bread crumbs, garlic, olive oil, lemon juice, sun-dried tomatoes, basil, pine nuts, salt and pepper in a large serving bowl and set aside.
When the grill is hot, place the clams in 1 layer on the hot grate and allow the heat to open the clams. They'll open gradually for about 5 minutes, then pop-open wide when they're done. Using tongs, remove the clams from the grill and place them in the bowl with the bread crumb mixture and toss together. Drizzle with the melted butter, and serve hot.
