a biger cam would do some good things for u like posted before u are noot even using the full potencial of those heads and intake......also if u going to be doing na passes maybe a looser converter to match a good size cam and that top end.......just something to go by i ran 13.0 at 108 with street tires and with out that intake u are using and a heavyer 4l80 but i had a way biger cam (236 236) and a 4400 stall .....with ur set up and a little biger cam i dont see why u cant go into the 12s na...i ran 12.0 at 108 with the 4l60 and the lsxr so i see no issues u going 12s

I think that 364RWHP is pretty decent from a 5.3. I dyno'd my truck on thursday at LMR AND ONLY PUT DOWN 324RWHP. I developed an intake manifold leak causing my truck to idle at 3k rpm while in park. I think that its from the o-rings that I installed b/c the o-rings that were provided with the lsxrt kit didnt fit. My set up is pretty close to this setup but im running the stock 243 heads.
