I asked him to post up pictures in his original thread but...... nothing.

 

Could be blowing smoke whith custom roots style I've seen very few ppl that has a custom roots style blower

 

And I was reading over his post he said something about active fuel management that's d.o.d you migh have to change to ls7 lifters valley cover to delete your turner migh have deleted it and that could also calls mis fire but as well not getting the oil to the lifter done seen this happen before but my guess what it's one of them problems you should have changed lifters in the beginning since u took the intake off all you would have had to do is spin the cam twice to hold the lifters up good luck man if u was here in Louisiana my guys could have took care of that in mins

 

I have been having the same problem on #7.. If you know someone that has a Solus and watch your O2 sensors Bank1. A faulty O2 sensor " Some common engine O2 sensor symptoms that you can experience are a rough engine idle, a misfiring engine, or an engine that hesitates or stumbles when attempting to accelerate." if you have done all that to the engine already try that next step.

 

the motor on the stand is not my motor

 

Whoever created the manifold probably used their engine on a stand for mock up then sent it to this guy? Not sure how that's fucked up.

I'm at a loss for what could be causing your misfire...

 

Most likely the case.

Turbo-LS7 Unless you know for sure that he does not have a custom roots setup then please stop with the accusations and name calling. Maybe you should look around the site more, there have been numerous custom Roots and twin screw setups. I had one of them.

 

Actually the guy is local but he builds a bunch of GM stuff and has a 5.3 motor in the shop so I wouldnt be without my truck for a month while he built the kit. Plus why would I make a thread with a problem to solve showing off someone elses truck to people who I do not need to impress on the forum?

 

yes sorry i started too and then i got a customer and went to lunch and when I came back to work someone closed out my window and I just never got back in there
