You won't know for sure what it is until you start tear down. Start with removing the valve covers - maybe it's not too bad. Keeping fingers crossed for you!

Should have been ok to drive as long as you kept the car out of the higher rpms. Good luck to ya.

exactly.
The engine was on life support when you put the cam in. The dyno took care of the rest.
As I posted... a brg is likely spun...

It was driven easy, must have just been tired. But thanks, can always use the luck!

I agree, it clearly broke on the dyno as it did nothing but lost power.
What is your opinion on a spun brg, and the motor falling on its face at 5,800 rpms? Would that make since, or was something else wrong with the motor do you think?

Any way that me camming it "incorrectly" could cause the spun bearing, or since I had a very tough valve train, the next weakest link in the motor would have been the brg on over rev? I read everywhere that a lack of oil is a big cause to spinning bearings, I would be at 60 psi on start up, and never drop below 40 warm with the ported ls6 from tsp. Just want opinions, this was my first ever motor "build" if you would call it that.

Thanks man! I ended up pulling the covers, and the valve train looks brand new, as I would expect for 400 miles, ha! Still no time to pull the pan, but I will get around to it sometime and will be back on this thread to let everyone know what I find.

Look at the data log from the dyno.
Could have well been the knock setting off spark retard = power drop.

Well, motor didn't begin knocking until the drive back home so I wouldn't think it would of set any sensors off.

Did you ever tear your engine down?

Any slight knocking would make the knock sensors trigger to cut timing and you wouldn't be able to hear it, that's the computer's way of protecting the motor.

I've heard knock while watching the computer pull out timing while logging before. Pinging specifically. It doesn't stop it. It just tries to help.

Driving untuned with stock injectors to the tuner is perfectly fine as long as the trims are still turned on and he doesn't go WOT or hits any high map areas. Now, if you changed injectors, then you have to drive there with the stock ones and swap there or swap at home and trailer the car.

The trims will correct back. A cam makes you richer at part throttle (low map) and leaner at higher map areas, which won't matter as long as you stay out of them.
