how reliable is the LS3? and why so big?
i have been thinking about the reliability of the LS3 engine as a daily driver. For some reason this engine seems more like a weekend toy type of engine that is only for 1 or 2 days a week.
is there any issues and how many miles can these engines last with proper maintenance? and how have they done being driven 7 days a week?
i thought that the 23 mpg rating was for the manual also but cylinder shutoff only works on autos. What should the epa be for a manual SS?
And why is it such a huge engine at 6.2 liters? Did GM really need that much size to make 420 horses? I heard Ford can do 400 HP with just 5.0 liters.
