Some of you guys are making this WAY too complicated IMO. My opinion here is lengthy... but simple. Main point in red for those who are lazy
Seems pretty simple to me,
So to point out the obvious and existing already
Stingray - LT1
Grand Sport - LT1
Z06 - LT4
Camaro SS - LT1
Camaro SS 1LE - LT1
Camaro ZL1 - LT4
Cadillac CTSV - LT4
Right?
Okay...
We know for sure the new ZR1 is incoming, its been sighted, we still don't know enough about the rumored mid-engine "Zora" to really speculate when it will even or if it will even arrive.
So, that leaves 1 of 2 options for the LT5,
the "Z/28" is a track bred car, the "Z28" is not as track oriented, according to GM and their history.
based on the photos we've seen, it appears the speculated car is rocking 305-315's on the front, which would suggest "Z/28" and definitely nothing supercharged above 600hp and is the track bred version as the previous generation was. Other wise what in the world would be the appeal of the ZL1? + they won't make any Camaro pushing MORE than 650hp because they will not challenge their own Z06 in a straight line.
This would suggest the LT5 is 1 of 2 possibilities.
N/A 6.2-7.0L and high revving for the Z/28 specifically
or FI and 700hp+ for the ZR1 specifically
Because the Z/28 we've seen will NOT be 600+ to compete with the ZL1 in a straight line, and the ZR1 will NOT be less than 650 (the Grand Sport fills that gap)
Just because they are trade marking the name and we know the LT5 will be a new engine does not mean it will be in both the ZR1 AND the Z/28, because IMO it won't be.
