The major R&D gets completed making just one engine but the use of the block/heads can be used to still make many variations of an engine. They do it all the time. If they made lets say a "302DI" it could be used in the Impala, Colorado, base full size using different cam/crank/manifold design/tuning to get the desired effect on said vehicle. it is the same thing they aleady do today, and its not really building a one-off engine that its been said that would cost an arm and a leg to put into the Camaro the specific cam/heads/crank etc. would just be specific to the Camaro. I would still rather see the 5.3L DI in there at 475hp though 7000 redline.

What makes you believe that the 5.3l is capable of putting out around 90 HP per liter compared to 69 HP per liter for the LS3? Is direct injection worth that kind of improvement?
