Can someone point me to good threads on or give me their viewpoint on the lifetime of a 5.7 hemi NA vs FI as far as the life of the engine. I would like to eventually add close to a 100 HP to the my 2013 and I not sure which route to take. I do not plan on going to the track much and I want the car to still last me a good 9-10 years. I am very new to dealing with engines etc.

Any input would be much appreciated?

Done right you won't see much change in the under 100k zone. Getting 250k miles out of a blown motors designed for NA might be a stretch. It's been done but rings often wear and oil consumption can increase.

The BIGGEST thing going modified is the work. You have a custom rig. So be willing to pay someone or learn to fix minor things yourself.
