If you really want something extra out of that 2.7 take the block to a machine shop and have them deck the block by .20 and take the head and have them deck by .10 and port it. DO NOT bore the cylinders it's a waste of time. For what you gain apposed to the loss of durability isn't worth it for a 5% of 150 HP gain. Get a stage 2 cam, headder and a highflow cat and a e-fan(like previously stated) I myself don't believe in using SC's or turbos I preffer durability and I can still use reg gas. BUT if it's a trailer queen by all means SC that bad boy
