This was a pretty awesome build. They out this together in 4 days!
By the way, it was not cheap. I bet the crankshaft was at least $2,000. The carb was probably $1,000 or close. Machine shop stuff, I dunno. I wouldn't be surprised if it was almost $5,000 to take an existing 400 and do what they did to put it in the car. Which isn't bad but I'd be curious what kind of power it is making.
I guess that's not really the point - they did it quickly and the result is very cool, not a drag racer.
