8-1 header on Destroked 6.0 engine dyno at 30psi

Destroked 6.0 with a Callies “ stroke crank, C5R heads, custom 8-1 header by One Guys Garage, and a Forced Inductions S491. This was back in March of 2020, I have since sold the turbo setup and the engine is in the car NA right now. The 8-1 was fun but it really hurt the top end power and RPM of this particular engine, if I were to do this again I would like to do larger primaries and collector size. It did spool very quick (contrary to popular belief), and made good low end power for its size though! 30 psi and 1500HP
