Because it was fine behind a 318, most people that bought a 318 car were using them as family trucksters.. if i was just making a car to drive and not beat on i would change the oil in it and use it. it probably made it 100k already without breaking..

In my opinion, this ^^^^ is the correct answer to your question. For a driver you can enjoy.


Now, if you're planning a swap to a high-suds 340/408/440/500 a swap is certainly in order.
There are many upgrades possible/available. 8 1/4, 8 3/4, 8.8, 9 1/4,Dana 60. Other than the 8.8, and the 9 1/4, direct bolt-in can be found.

Personal preference? For an inexpensive, high strength rear with great parts availability, an 8.8 is hard to beat.
