Hello all, I am building a 348 for my 1956 Belair sedan. I have always loved the 348 and 409 engines and feel like it will give it a good nostalgia feel. I have had the block machined and cleaned up. I have also picked up some NOS venolia forged pistons for it as well. One question I had is the orientation of the pistons. I have them mocked up in the first bore but don't know if I have the 180 off. Any help is appreciated.
