Hi guys. My friend and I are putting together a 440 for his duster out of extra parts we have laying around. Can you give me a hp guess. Engine is 76 440 almost no cylinder wear at all. New rings and bearings 484 cam. Heads are 452s shaved .050 2.14 intakes and 1.74 ex. Pocket ported and gasket matched. Performer rpm intake and performer 800 carb. We will use a .020 shim head gasket to help with compression. My guess was just shy of 400. What do you think?
