Hi everyone, new to LS’s been doing tons of research but there’s a lot of info spread out, was hoping I could get some good suggestions on this thread.

im pulling an LS1 out of a 04 GTO to swap into my Lexus, the engine has 71k miles on the dash... but it sat out for a while and most of the accessory pulleys are rusted, engine turns over and oil was good 👍🏽.

any suggestions as to freshen it up? Should I changed/update anything? (Im already planning on doing gaskets, water pump, a/c comp and alternator/starter) but anything internal I should worry about?
