4.6 to 4.0 swap? Feb 9, 2009 0:09:42 GMT -6

Now that we know a 4.6 Northstar will work in the Aurora, what about putting a 4.0 Aurora Northstar into a Cadillac? I realize the desire to do so might not be there, due to the difference in power output, but I'm still curious. The main reason for my curiosity is that I'll have a perfectly good 4.0 Aurora Northstar engine sitting around after my swap is done.

Who knows; maybe I'll be able to find a good deal on a Cadillac that needs an engine.

Any thoughts?

Yes. Sell that engine to somebody who has an Aurora that needs an engine.

True with head gasket problems imminent many find themselves looking for good low mile 4.0 engines.

As far as the original topic of this thread goes... I have not yet found a host vehicle for my leftover 4.0....

I was "this close" to pulling the trigger on a used '99 STS, but I had no way of picking it up. Plus it was a couple hundred miles away from me.

don't you guys know that speed was banned forever? i wouldn't be holding my breath for pictures lmao why would anyone want to swap a 4.6 with a 4.0 unless they blew the 4.6 and just happened to have a 4.0 laying around? this seems counter productive
