Yes. Shifting at 7300rpms and running out of fuel. No KR what so ever and no hint of valve floating. Stock springs rock. I honestly dont know anyone who has ever broken a stock spring. Dont get me wrong, there coming out this weekend, but they have lasted since July on high revs and .560 lift.

At 6600rpm its pulling about 45lb of air through the MAF. From there to 7300 it really doesnt increase anymore.

Just went and got some pizza and loged my Blazer and it pulls a whopping 23lbs of air at 5000rpms. What a difference.

Holy **** batman ... your truck is waiting on disaster! Running so low on fuel it dies when you let off, and running stock springs up to 7300!

What cam are you running?

 

The spinning that high was just some trial and error kinda stuff. I just wanted to see if the valves would float. Its back down now. As far as the fuel i guess 32#ers at 63psi aren't enough.

I'm running the Lingenfelter GT1. Its pretty nasty, but not too bad. If i could just get it to fire up right. Idle is nice and choppy.

 

you know, 7300 rpm is screaming....wow....I'm impressed.

 

any sound clips?

 

I'm sure i can get one of it tomorrow. Maybe even a 7k+ screen shot if i can figure out how.

 

Please do something about that!

 

Need this damn 5.3 to let go so i can get the 408 on order.

I never thought it would last this long.

 

Keep running it like you were ... that'll help it out.

Anyways you could get a video clip of it screaming at 7300 rpm? I'd like to see that one.
