It'll be branded Cadillac, first.

Interestingly, if we can believe the 4.5-liter rumor, and if GM can get the same specific output as it can from the LF4, a 4.5L "LT5" V8 would make 580-hp.

It may come down to weight. One of the original LT5's weaknesses was it's power density...it is a heavy engine. Hopefully a new "LT5" would approach the light weight of some of the Gen V8s, such as the LS7 which weighed about 455-lbs.
