I have a LS2 402ci with -3cc relief flat top pistons trick flow 215cnc heads opened up to 4" bore and we did a valve job and dropped in some 2.055 intake valves, Harland sharp 1.7 roller rockers, ported 90mm fast intake, with a nick williams 90mm tb. 85mm lid and 85mm SLP MAS, motor is about 12.3-1 compression and will be tuned for pump gas, Futral Hardened push rods, EPS custom cam 246/255-613-632@113+2LSA all this through a PTC built th350 tranny with a PTC 8" 5000 stall converter and a strange 12 bolt rear end with a 4.11 rear gear and 28" tall tires.

Hoping for low 10's @130+mph on the motor. How much power..

It better be at least 620+ engine dyno!! LOL You don't think it would be more than that with the 12.3-1 compression ratio?
