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
In 1978 my dad bought a Prototype Racing engine 331ci for his circle track car that was dyno @ 585 HP @ 8500rpm, car was fast, now today the same size engines are going the same speeds and times around the track but are claiming the engines are making 750-800 + HP lol
