Location: Sherwood, Finland | The 318 in my'60 Plymouth Fury is starting to show signs that it would be time for a rebuild. I haven't really put too much thought on it as the car still works pretty well. However, a fellow offered me a rebuilt 361 that he says is from 1965. The engine seems to be decently rebuilt, according to documents I've seen. The most appealing thing is the price: it's cheaper than rebuilding the 318 would cost. The question is what needs to be changed if swap to 361? Here are a couple of things that come to mind:
- Front springs
- Engine mounts
- Exhaust from headers
- Transmission. Will the original 3-speed TF work with 361?
- Generator, starter, power steering pump and fitments
- Fan
- Radiator
Can't think of anything else, but I'm sure there are more knowledgeable people here who can add whatever I've missed. |

Therefore, your torque converter and transmission will not be able to be installed to the 361. If you use the newer trans that actually mates to the later motor, I believe you will have issues with push button functionality as the newer trans have "Park". |

Location: Sherwood, Finland | Thanks jboymechanic! Just the kind of knowledge I was after. Unfortunately a showstopper, since the transmission in my Fury had a costly rebuild by a professional last winter. Works like a dream now and I expect it to do so for the rest of its life. |

Your main issue is that the motor is from 1965, so the crank flange will be different that your 1960 motor. . Actually the 318 has the SB bell pattern vs the BB pattern. On the SB there's a bell & crank flange change beginning with the '62s. |

| Agreed with JBoyMechanic, I've run into that issue.
