I see where Scott Brown built a 496 pump gas Hemi 6 or 7 years ago that made 851 horse 1.71
Was that on a dyno or track proven numbers... I dont have a lot of faith in dyos lately.. I would really doubt that the OP engine made 1004 hp on MM dyno... we have seen other engines that came off that dyno and the numbers were NO WHERE NEAR what the track showed
