But what that being said, I wouldn't really consider these shorty headers.... I would definitely say they are medium length. Either way, I have seen quite a few dyno charts of 416 LS3s with parts that should make less power than mine. I have seen a few LS3 builds similar to mine - to the wheels with worse HCI combinations (but the same heads) are getting at least 580 rwhp and 520 rwtq. The peak HP is at over 6k rpms, so maybe the medium length headers will hold me back a bit up high. I would definitely be happy with 580 rwhp & 520 rwtq, but I am expecting it to be more than that. We'll see....

Quite the endeavor. Those parts are looking pretty awesome so far.
