Doubt you can do it at 11psi.
with a 5.3 and a cam thats around 500hp to the ground or so. You will more then that power to get an ex cab into the 11's. Good luck with the project.

I am going to be sorta Sadd if turbo power cant do it..... Not stuck on 11psi... but less then 14.... My truck went 10s on 13 without much trouble at all.... and I expect my D1 ex cab ls6 truck to be deep in the 11s with Procharger ... So i hope a Cammed 5.3 with a pretty Hot tune can make it into the high 11s on around the same boost pressure... or you think i need Twins on a 5.3 to do it Rick? Maybe a Single 70mm will not Cut it but can you spool twin 70s with such a small motor?
Mine is a 5.7 ls1 in an xcab 4x4, 5400lbs. When I had the MPT70, .68 a/r and 14 PSI, I've when 12.2 @ 110 at 4800 elevation, about 8k DA. I think you could do it.

X cab into the 11's I am sure you can get there but I doubt 11psi mid 11's thats all. Single will get you there just more boost needed, and really going to depend alot on that 60ft. The lower that is the easier it will be. Or the harder /high HP your going to need on the other side in MPH. No need for twins.
