It will be quite interesting to see if you can do it in that big crewcab. I've been doing a lot of thinking about the manifold issue. Richard@WCCH did some testing on the L92 truck intake and LS3 intake both hooked up to a set of L92 heads which we know flow well over 300 CFM stock. The L92 intake only got around 250 CFM through the heads, whereas the LS3 intake managed 290ish CFM. That doesn't tell the story on the low end airflow and velocity that the truck intake can produce, but the top end airflow difference sure is striking. Now, how this relates to your setup....huge flowing heads, but severely limited by the intake manifold. I bet a swap to the NNBS 4.8/5.3 manifold would be a very beneficial swap for you. 007GMC saw 15 rwhp/18 rwtq on his stock cammed LQ4. Food for thought..
