'05 Hemi ?'s

My motor is an 05 car engine, (I’ve swapped to the later coils/valve covers for looks)
Mine has had cam and long tubes with 6.1 valvesprings and pushrods since I first fired it up 4 years ago. It now has Eagle heads and 6.1 intake...

Even with the cam/longtubes it still ran out of power about 5600... I drive it about 1k a year, and race is 4-5 times a year, and drive like a goon pretty frequently when it’s out. I have my limiter set at 6300, and have had it bump off the limiter more than a few times when my auto trans occasionally decides to hold 2nd too long...

Long story short, I agree with these guys if it’s a well maintained motor you’ll be fine running it as is. With the cam just be sure you do springs to match. I wouldn’t worry about forged internals if you’re building a regular street car. Keep the AFRs and timing safe and you’ll be fine... Add boost or nitrous and then I’d worry.
