No word. (Preface - since we already know we're getting SS, I'm only bringing this model up since we have no confirmation of anything except that it is not dead) If I'm not mistaken, 'Father's stated that original plans for the Z28 have changed, but to what extent, no one here either knows or can say. We don't know if it was to have the LSA or not. We know the SS doesn't have it but that's about it. I think the only car, for now, to have this engine is the Caddy', although I'm wondering if the Z06 will pick it up since it's my understanding the LS7 is going bye-bye. Unless the Gen V is ready to go in production soon, I can see the LSA make it into that car since it makes more power and torque; it would need it to overcome the additional weight it would add to that car.
Beyond that, I don't have any ideas. I'd welcome any information I've missed though
