I recieved a bit of info about the motor.
LS2 with forged pro Pistons, scat rods, double row timing chain, standard Comp. L98 heads with aftermarket valves, springs and pushrods. LS2 HSV cam, 24 x reluctor wheel. 25% under drive pulley. Fast throttle body and standard injectors. HPC coated Pacemaker extractors, LS1 ECU, custom harness.
The sump will come off to get modified with better baffles and maybe larger capacity. Will have a look at the engine condition.
