Reply With QuotePlenty of opinions in this thread. Although perhaps needless to say, mine is that the swap is worth it if your 300 is coming up for rebuild. Engineering it is the struggle.

The 4BD1T is probably going to have better low down torques, and certainly more rugged, durable and reliable.
On the negative side, it is (a lot) heavier, rougher and a lot more work to install than overhauling and upgrading your existing engine. Two key problems exist - the required flywheel housing and bell housing are scarce as hens' teeth (means you may have to get custom ones made - $$$), and you need to look at whether you can get engineering approval before even starting. This will depend on the date of your vehicle relative to when the 4BD1T ceased to meet ADRs. This willo be critical to whether you even want to think seriously about it.
