I am swapping a ls6 into a 57 Chevy for a friend.The engine was out of a 2004 Vette z06 .It has a low boost California legal procharger on it but is otherwise stock.Since this car doesnt have to have to be smog checked the owner is talking about a cam upgrade.The engine is on a stand at this time.The car will be running long tubes with a 3" exhaust.I am sure it will need valve springs.pushrods and a trunnion upgrade+ a trip for a dyno tune when done.Trans will be a t56 with 3.73 or 4.10 gears.Anything I am missing?

 

check ifn the bottom pulley is pinned. If you decide to up the boost it will be needed
