In '57 the engine code letter B is for the 272 Y-block V8 with a 2bbl carb.
Also indicated by the prefix letters ECG in the engine block casting number. . |

One slight error in the picture of the engine code listings. It says for code C it was a 292 4V. The 292 in '57 was a 2V. Sal |

Re: Engine size The first character of the serial number tells you what engine it had from the factory. 7 indicates '57 model year. N indicates Norfolk VA assembly plant. G tells you it's a Custom 300. Now, unless you know the history of the car from day one, don't assume that the engine in it matches the serial number plate. All Y blocks look pretty much the same externally, so check casting numbers on block and heads to be sure of what you have.

And it actually goes beyond that. All look for the ID MARK on a 312 C/S and if there assume the engine is a 312. It may be a 312 crank was used on a 292 making it a stroker. If you want to be 100% sure of what you actually have and intend to rebuild/modify is to put it on a forensics table. |

Re: Engine size I understand why owners are concerned about the true identity of their Yblocks. After decades of them being around, being rebuilt and modified, actually knowing the cid can be a challenge. I remember way back in another life (almost), I worked Ford Parts at a dealership in the metro Detroit area. A guy comes in, asking what engine is in his '55 F100. I went over to his shop and he had Yblock parts scattered from June to Christmas on the floor! From 239s to 312s, a true duke's mixture. After considerable debate and discussion, he/we concluded that except for the 239s, he could use any of them for his '55. He was building a driver & not a show piece so casting #s weren't an issue. Later when asked what engine he had, he simply said "one that fit". So I guess only he and his doctor knew for sure. Recently I gave away 3 mostly complete & rebuildable Yblocks, ID #s said 2 were 272s and one 292. And sent other one - yeah a true 312 - to the scrapyard.

Re: Engine size An owner usually wants to believe an engine is original to the car, if that's what he expected, or at least as good as he paid for if it's been knowingly swapped or rebuilt.
But not an undisclosed lesser/older/smaller engine, which can often be the case from dubious sellers. Depending on the vehicle, and its new owners expectations, a large-ish portion of the perceived value may be tied up in the engine, often with good reason. The marketing goals for classic and collectible vehicles by auction houses leads to increased prices for the characteristics deemed more desirable on a given vehicle. IE: the promotion of "numbers matching", which filters into the collectable vehicle hobby and resale sites. . |
