The 348 Chevy didn't appear on the scene until 1958 (so the dummy that told you that, is stupid) and then usually in a larger truck and eventually was replaced with the 409's until early 1965... and the 305 wasn't even thought of in 1957..
Early (1956 production) 57 Chevy passenger car v-8's were 265's. The 283's replaced them in 1957.
