"Midnight Modified"
612 HP
579 TQ
But carb needs some tweaking.
Our 775 Demon made the 612 HP
And the 850 Holley made the 579 TQ and less HP. Visiting with Holley.
But it's a good start.

I asked this on Facebook, but will ask here as well - at what RPM did you get the torque and HP peaks? And what cam are you running?

We are not done yet, so I have not looked at the data close.
Recall about 6000 HP and TQ at about 4000.
Camshaft is actually some LS lobes that Comp Cams put together for us.
We did cheat here, it is a hyd. roller camshaft with solid lifters adjusted about .008 lash hot.

Ok, thanks. But, that's not cheating - it is just smart engineering.

Wow!!! Nice work Tim!
I really didn't think you were going to be able to pull that kind of horsepower through that manifold!
