LS3 Block stout enough for 427 build?
Just thinking a little ahead into the future and may start collecting parts to build a 427 in motor. It will use the procharger I already have, plus I'll probably get some CNCed heads.
Is the LS3 block stout enough for a 427 build up. Probably looking to make 650-700RWHP on pump gas for a street car.
Do sleeves need to be installed or are stock liners good enough?
