For reasons beyond us, General Motors actually considered the idea of placing the LS3 V8 under the hood of the 2014 Camaro Z/28, instead of the LS7. While we know The General went with the better choice, there are definitely some positives and negatives to look at when comparing the two motors.
Reasons to use the LS3:
- Lighter weight
- Better mileage (who cares, right?)
- Utilization of existing components (no new fabrication)
- Keeps costs down
Reasons to use the LS7:
- It has over 500hp and is hand-built
- There’s bragging rights to having a 7.0-liter engine
- The most powerful motor is always the best choice for a track car
- The LS3 is for sissies
While Chevy had kicked around the idea of using the LS3 in the Z/28, it would not have been in its current. The 6.2-liter mill would have been tuned, bringing the total to about 450hp, and the vehicle would have been equipped with dual-mode exhaust. Still, it would be no LS7, that’s for sure.
