I have two matching set ups off a boat with twins. We are installing blowers and the customer wants to sell them they are 2 years old. The intakes are Merlin X high rise aluminum Intakes Rec Port. They are Marine with the brass inserts. I also have a nice set of 850 Holleys that were on them. If you need pics let me know. 275 per carb and 250 per manifold. A 1,000 takes everything.
