That would be pretty exceptional with those mods. 460 whp on stock heads? 500 on heads/cam? I'm no expert but the average LS1 numbers I've seen have been 400 or a little less on stock heads and 420-450 on heads/cam. Keep in mind I'm not counting nitrous as a "bolton", The LS2 car I'm thinking of had intake, headers, exhaust, the cam, and tuning. 460 to the ground.
