That is Phil's car running a 10.85 the car has a Callaway body kit on it and the engine was built by LPE.
The LS7 engines cylinder sleeve's strength aren't the weak link for FI. The weak link is actually the length of the sleeve. Plus the newer LS3 blocks are built for FI with more nickle content and support. Unlike the early version's of the LS3.
The new ZR-1 is a total animal. Also alot like our ZR1's where they start pulling well at 100+ MPH. The new ZR-1's kill us in the torque department. As far as handling well let's say that the ZR-1 is light years ahead. Approach them with extreme caution.
Hey ....technology moves on
