I put a mild 390 in my CSX. I bought the motor from an engine builder off ebay for $3300 shipped to my door. It's a 400-425hp motor. It has been flawless in performance, and reliability. It runs plenty cool, much cooler than any other Cobra I've driven with. As for looks, my 390 is visually more "correct" than most any other Cobra out there
.
If you're not looking for crazy hp and you want a nice reliable motor, I'd go the 390 route.
