Think about it............
The 4th gen V8 went from the LT1 to the LS1 when it got it's refresh in 1998. The LS1 also went into the "new" C5 Corvette one year prior in '97. The C7 Corvette is getting the "new" LT1, so what better time to use it in the Camaro than in conjunction with the refresh.
The "new" LT1 is more efficient & powerful than the LS3 and they've managed to work out the issues with VVT and cylinder deactivation so that it'll work with auto transmissions, so it could replace the L99 in the auto cars as well.
Doesn't make much financial sense to build and support 3 different "base" V8 engines (I'm leaving the LSA and possible LS7 out of the mix) when they could do the same job with only one.
Mkes sense to me
