So the 3 in front of NE57 doesn’t indicate anything? And it is a 392 though? 2000 seems pretty legit price for it as long as there’s no damage to the block or heads I assume?
Yes, the 3 doesn't mean anything. Is it a 2x4 intake or just a single 4?
Edit: 72blu has it correct. I used a book form the 1990's rather than get off my can and walk to the library and get a book from 1960. And that says what 72blu posted. The 3 denotes the 2x4 intake etc.
