Okay guys new here and need some help. I have a 09 5.3 silverado I just bought a 6.2 block the other day and wanna get started on it. What parts can I swap over to the 6.2 to use them and what else do I need other then the internals? I will be using ls3 crank rods and pistons. Undecided on intake right now maybe y'all can give me some pointers. Will try to get my hands on some 892 heads but wanna see what I can use from the 5.3 so I can sell the rest of what's left and speed up the build.
Thanks guys any help is appreciated
