Different Engine Case Numbers
Question for anyone - I bought a '72 2.4L MFI used engine to rebuild. After tearing down the engine I noticed that one engine case is a 3R and the other is a 4R. Is this normal? Or is it more likely someone replaced one of the cases?
Thanks |

Odd and even, right and left.
There is a set of numbers on the top centerline that are on each side to show a matched case. Bruce Last edited by Flat6pac; 05-16-2018 at 03:39 AM.. |

You will need case line honed if it’s not a match.

The 3R / 4R combo is normal, so no worries there. Just be sure the mating numbers on top match. Here is my thread on case revisions:
911 engine case Revisions Please PM me with all of the numbers on the case to add to my database. Steve's comment is very important.
