I have an 85 Dodge Daytona with the 2.2 turbo engine. Currently it has the stock 85 slider cam with 240-240 Duration. I have been wondering what kind of fuel economy benefits I would see if I were to swap in a 1989 model year cam that has 228-228 Duration. The 1989 cam is a roller cam.

If I could get a cam for free I would just try it out but it would probably be expensive to get one at the wrecking yard so I must figure out if it would be worth any fuel economy benefit.

Perhaps this sort of cam swap will be comparable to a geo metro cam vs a metro XFI cam.
