I have been referencing the 3.6V8 swap, you are bringing out the big boy V8's here, there isn't much comparison, these are$4-6K+ motors, with eons of development past the I5. The 3.6 is comprable in price to an I5 swap, now these newer engines you are talking about use variable intake, variable timing, and very advanced versions of Motronic to acccomplish their output, no comparison.
Granted, I have put a lot of time and a reasonable amount of money into 80tq, not a ton though, I could never afford to drop $6K on a 4.2 V8, sure, $500 here and there I can do, but not a chunk like that, I have not spent anywhere near that on my car. If you have the money to use a 300hp V8 in a swap, and are able to engineer mounts that will safley support the engine, go for it, it would be a great project.
