Lost, need advice!
I am starting to build my 5.3 for forged internals, and turbo. Right now i have a bare block from a 05 sierra, This is going to be bored to 3.905, (5.7).
I am trying to get the compression to some where around 10:1.
I know that im wanting Mahle pistons, Ls6 cam, PRC stage 1.0 LS6 ported heads. SCAT I beam rods.
I am having some trouble figuring out what my compression will be, and which pistons i would need to get to make the ratio right, also what length rods would be suitable?

Diamond 11500. 6.098 rod. Oh, after I looked that up I saw you want Mahle. The Diamond is -2 cc and will give about 10.25:1 with LS6 heads. They figure that with 11.8 cc gasket volume, and the pistons sticking out .010". They weigh 408g.
I don't have a Mahle catalog, but maybe the info will help you pick one of their pistons.
