Injectors and Compression

I have a 2005 Silverado with the all aluminum 5.3. What size are the fuel injectors and what is the cylinder compression? I have some *** whipping to do on a Mach One and he wont race my TA so the truck needs a 150 shot
Thanks
Mike

i think the compression is 9.5:1. i read it somewhere but cant remember where. i have the same motor in my 05 sierra. not sure on the injectors though. look around on the performance truck tab at the top of this page.
