That idle sounds killer. Kind of an oddball question but how hard is it to find an LS3 and how much can they be had for? I’m wanting to build a 3rd gen Camaro with a single turbo. Goal would be 1000-1200 horse. I saw a 5.3 iron block on Facebook and that got me thinking too. How big can you bore and stroke a 5.3 iron block to? I know aluminum blocks you can’t hardly bore them unless you resleeve it
