You're right Gary,
I never saw the claim on the HP.......I was going to say I used to run a ‘69 Camaro that made 563 on the dyno at 3000 rpm with a normally aspirated motor. Only prob was 105 octane was getting pretty expensive since lower would pre-det. I may be driving impaired (I’m not), but that mutha was a challenge to drive. It was street legal, but near impossible to drive with a rear-end spool on a morning that left some dew on the street. (bump…. Bump…… spin…weeeeeeee)
Just cruising around, I had to keep the hood opened 2” to keep it cool enough to keep from vapor-locking.
I’m seriously doubting the ability to make the kind of horsies he’s claiming here even with a really great computer.
