Disappointed in numbers.

I just installed my night fury cam in my 2012 ls3. I also have have TSP 1 7/8 LT headers and roto-fab intake. Really disappointed in numbers. It was 81 degrees really nice day. Dynoed on a dyno jet

WOW, that's a lot lower than what others have posted. I'm sure it's in the tune.

There are guys claiming 500+whp with the NFC. Don't think they have head work either but I could be mistaken.

That car or dyno has problems. It peaked at 5600rpms. I'd look twice at the valve springs, pushrods, and/or rockers. It's also possible the cam was installed 4 degrees off with that power curve (a tooth)

Bingo! 5600 peak for a night fury cam; no way!

My uncle, dad, and I. My uncle has swapped many cams he did the valves and double checked them. We cleaned every push rod off before install. All rocker arms are in the exact same spot. And on the gear we even took a picture of the dots to make sure it's exact.

Did you make sure you were at TDC when you aligned it?

What springs and what pushrods sir.

Sure did. The PAC springs. Everything that came in the night fury racing package. Could hearing it help any to tell if something is off? Or will that not make a difference cause I can get a video

Hearing it probably won't help, but we'll all take a video!

I agree with these other guys. Retrace your steps and try to figure out what the deal is. You're right to be disappointed. Something isn't right.

Mine dynoed 475 rwhp my neighbor and wifes car dynoed at 486 and 492. No head work on any of them. I would say tune or something in the install like little88 asked.

I think 429 is onto something. I'm not sure how the tune could cause it to peak early.

I agree. There's not 30rwhp left in the tune unless the timing is totally jacked. Have you base lined on that dyno before the cam? That's what I want to know.

Early peak is only determined by camshaft valve events, not the tune. Cam could even be ground wrong. If you had degreed the cam (obviously you didn't) you would already have the answer you now have to look for. Live and learn.

When installing the push rods when placing them is there a slot or some kind of alignment groove farther down to sit the pushrods or you put them in and there set?

When I install the pushrod I make sure that the tip is on that lifter cup. Ill push down on it and feel it compress and decompress. That way I know it's on.

I installed this same cam myself and had it tuned by a guy that came highly recommended from some guys who had LS1 cars. My car dyno'd 455/425 on a dynojet and he had my A/F at 14.1. Way too lean for my taste. I ended up making the drive to Lethal and had Shawn redo my tune. The man is thorough and took his time making sure everything was spot on. We put my car on his dyno jet and I made 484/461. It was also 100 degrees in his shop.
