Nice numbers! Note made on the cam selection, though I would probably prefer a step up or two. How does that thing idle, like 700 RPM?

In the video it was idling around 1000-1100 RPM. Didn't try to see how low it would go. Engine needs to make at least 9" of vacuum at idle. Not sure if he could have gone any bigger on cam for this.

I was looking at the dyno sheet again, and it made 550 FT. Lbs. or better for a 3500 RPM range. From 2400-5900 rpm. That's a torque monster there. A 500" Caddy engine peaked at 550.

I put the dyno run into a graph so it would be a little easier to visualize

That's a pretty flat torque curve. It's gonna make that 69 Bird actually fly!
