I doubt if you could go this fast @ 3800-3900#? with much less than 1000 Dyno hp. There is talk of close to 9000rpm. What would that take? SS/AH style valve train. Biggest bore possible. If I was a betting guy I’d say 4.600x3.500. The plenty of time developing the intake and cam. Can’t even imagine the amount of time, effort and cost of this build. Congrats to Rick, Dave and their team. Us mortals still need light parts and headers.

If you go to their FB page linked earlier, there's an in car shot of a 68 Hemi running every bit of 9k on the tach for 1st to 2nd. Such a unique sound through that exhaust. Unreal to say the least, I'd assume every single part on the car is changed/modified/tweaked. If they are sandblasting fuel lines to open them up for more flow, they're likely doing something to the exhaust piping too. Every little bit helps.
