Re: Bought my old K5 back, now receiving a 5.3 swap...
I finally hooked up a boost gauge on Saturday and much to my surprise I am making 10-11 psi when the kit is suppose to be 7 psi on a 5.3 litre.*So I borrowed a SnapOn scope from a buddy and took a look down a spark plug hole. Sure enough, flat top pistons and until at least 2007 no 5.3 had flat top pistons. So it looks like I have a 4.8 afterall.Still making more than enough power so I am not too upset about it, don't have more than $200 in the long block anyway.
