I found this on another forum posted by a member making an educated prediction about the LS3's power ratings... seems to be very logical and well thought out....
"There is a lot of talk about the new LS3 but GM hasn't announced any horsepower ratings. I figured I'd take a stab at predicting what it might be.
Looking at the hp ratings of the recent LS motors, we have...
LS1 -- 346 ci -- 350 hp -- 1.01 hp/ci
LS6-I -- 346 ci -- 385 hp -- 1.11 hp/ci
LS2 -- 364 ci -- 400 hp -- 1.10 hp/ci
LS6-II -- 346 ci -- 405 hp -- 1.17 hp/ci
LS7 -- 427 ci -- 505 hp -- 1.18 hp/ci
LS3 -- 378 ci -- ???
The advances in technology are evident when you see that GM was able to take their 346 ci engine from 1.01 hp/ci to 1.11 hp/ci. This level became the norm for a "base" engine as the LS2 came out at 1.10 hp/ci.
Conversely, we have the higher performance offerings of the LS6-II and the LS7 that reached 1.17 and 1.18 hp/ci, respectively.
So, what makes sense for the LS3?
I my opinion, if you consider the general advances in technology plus the few extra ci, then the hp/ci will be higher than 1.10 and 1.11 above. Also, if you consider that it is still a base engine, you would expect it to be less than the 1.17 and 1.18 hp/ci.
An interpolation of the above results in 1.14 hp/ci which means 430 hp for the 378 ci LS3.
430 hp is my prediction"
I know the topic has been beat to death, and the speculation is all over the place, but i just thought that his logic was interesting....
