I'm going to put a remanufactured LS6 in my 99 Camaro SS. I hope this will work with my Flowtech headers that are already installed. The engine is rated 405hp just wondering what some average longtubes would do to this number. Hopefully about 360 rwhp? Standard LS6 intake manifold.

 

Hmm... I know of some LS1s with headers and some bolt-ons that are putting out nearly 360 RWHP, so I would think more...
