Location: Northern KY | I have 2 1957 plymouths; Both have the engine identification number on the front of the block on the passenger side, 1737928; however, one is a fury with a single four barrel intake, and the other is a savoy with a 2 barrel carb. / intake. (The fury is in terrible, horrific shape and is essentially just a shell, but the engine is "gold colored" unlike the savoy - which actually runs and drives).
Is there a diffence in cam specification and heads between the two motors? I assume they are both 301 poly motors. I wanted to take the four barrel and carb off the fury and switch it to the savoy. Should I switch the cam as well, or does anyone make repo / performance cams for these motors ? Any help is greatly appreciated.... thanks much.  |

You should have no problem putting the 4 bl intake on it. If I was going to change cams, I'd get a cam from someone like Chris Nielson that is new & known specs. |

That same casting number is used on the 318 poly engines also, but being a 57 engine im sure it is a 301 also. |

Location: STL, MO | See if there is a number stamped on the drivers side under the head on the front of the block on the gold engine, then see if there is a F stamped in front of that stamped number it may be crooked or on a angle to the stamped number. |

Location: Williams California | The numbers you had given are just casting numbers. As Steve, above, has said, check the machined area just below the left cylinder head, P31xxxxxxx designates 301 cubic inch for '57, if FP31xxxxxxx it is the Fury 318 for '57.

Location: Northern KY | OK.... kinda wierd, but I'll tell you what I found.. On my 57 savoy, there was absolutely NO casting number on the front left hand side of the block, below the head. (and it is as clean as a whistle). On the 57 Fury, the casting number MP8 134927 was identified. This is neither P31xxxxxx or FP31xxxxxxx Not sure wat the "M" signifies...... What gives ?? |

Location: Connecticut | An MP8 engine is from a 59 Plymouth. A factory replacement block may have been swapped in for the original block and not stamped with the engine number. Ron

Location: Northern KY | OK.... well, thanks for the info on my 57 fury; guess it had a 59 engine swapped in it some time ago for the origianl 57 before I bought the heap; so I can assume it is a 318 instead of a 301 ? |

Location: N.W. Fla. | Either way it doesn't change anything as far as intake, carb & cam is concerned. |

Thats the good thing about those 2 engines, most parts are interchangeable.... |
