I agree with the information stated here. With one comment on the section where this is posted. It would be more fitting in the Non-tech forum as to the lack of adding useful knowledge to the model specific.
Other than that welcome to the forum! There are many swaps that will fill your power goals. It sounds like you might not want the hassle of a turbo swap so check out the V8 section for most of your drooling needs.
My thought would be to check out the BMW, 2j, Mercedes straight six swaps. Many have close to your power goal (some tuning and a few parts) have A/C, power steering options and they are not all to common on the boards. Very reliable and all the fun you can handle. 350-400 in a 2500lb car is CRAZY!
Enjoy your time here.
