I have been talking to Katech and MTI racing on motors. The following are the two choices I'm considering but cant make up my mind on which way to go. Any input or suggestions would be greatly appreciated.

This is the one from MTI:
Built 6.6L Stroker engine
LS2 based
Forged pistons, forged rods, balanced and blueprinted
MTI Racing CNC ported heads
Ported LS6 Intake manifold
MTI Racing/Comp Cams private label Camshaft
MTI Racing lightweight valvetrain (valvesprings, locks, retainers, seals, seats)
comes with valve covers
comes with oil pan
550-575hp depending on cam aggressiveness

This is the one from Katech:
Estimated 650+hp
7500rpm redline
427ci
LSX based
Carbureted
Includes Katech valve covers, coil relocation, coils, electronics, and carburetor
