I am running a 383 10.8:1 with a SCAT 9000 crank, sealed power hyper pistons with coated skirts, stock pm rods, M6 with 3.42 gears, if you guys need any further info to give me an educated answer just let me know?

 

I wouldnt run over 150 hp with those pistons, you may get away with 175 with a super conservative tune but the extra 25 hp isnt worth it. What are your ring gaps and did you debur your piston tops and combustion chamber?

 

not sure my ring gaps off hand but yes everything is clean inside the chamber

my motor from top to bottom is a ported lt1 manifold, fully ported 63cc lt1 heads with 2.00/1.55 cc305 with full comp cam valvetrain, 1.52 roller, scat 9000 crank, sealed power hyper pistons, stock rebuilt PM rods, 30# inj, 52mm tb, high pressure oil pump

 

I'd probably stop around 150-175rwhp. Make sure to tune it with a wideband O2.

My stock bottom end took 180rwhp shot for quite some time before expiring due to a faulty fuel solenoid. With a 92 n2o jet, that should be around 225 at the motor.
