Aftermarket Holleys all mount the same regardless of what vehicle they are on. The 390 you have would be a Holley square bore. Summit has an adapter plate part# SUM-G1406 for $52.00 and Jegs has a Moroso brand part#710-64966 for $55.99. Keep in mind that these are for adapting the Holley 2 Barrel 2300 series carbs. The stock Motorcraft 2 barrel used on AMC V8's will also fit these adapters.
