    I need some help before I go to do this, its a buddy's silverado. He has a 2007 White Silverado ext. Z71 and has the 5.3L. So I have a few questions... What is the compression ratio on this motor? Also what should the compression ratio be for 10PSI? His purpose for the truck is weekend off roading and daily commuting, just looking for a bit of extra power.


    I forgot to mention its a 1500 GMT900
