Just logged a 540 mile trip to sell my C6 Z06 to a buyer in Las Vegas I did the trip in just over 8 hours. 1 pit stop/refuel in Bakersfield 69 MPH speed average at 27MPG fuel economy........in my book the LS7 is the most KICK ASS motor to ever come from GM. My old Audi R8 buddies with their 420HP 8100RPM redline 18MPG 4.2L V8s used to be in complete disbelief at the mileage and power of this 7L monster! I'm glad the 2014 Z28 has extended the production of this awesome unit.
I don't think the new generation of Direct Injection motors will have the same legacy...for starters who in gods name decided to put the water pump in the stupid location! Don't even get me started on the issues Direct Injected motors have with build up on the backs of the intake valves.....a MAJOR problem that has yet to be solved by GM, VW, Audi, Porsche, Toyota, BMW.....they all have build up problems! Want to tune a DI motor....I'll bet those tool steel cam cores will run $750.....make sure to get the high pressure pump cam lobe right......
