Haven't seen a price nor an official HP number. I don't want to hear it's 556 bcause the Cadillac is because the SAE standard requires the motor to be tested in the configuration in which it is in that car. Despite the LSA RPO it isn't really the same. The honing with the deck plate and different intake and exhaust routings ought to make a couple HP diffrence anyway I would think.
