Yes, and then some. I've seen that video before, and it's excellent. It tops out at 7K RPM.

I set my rev-limiter to 9K. My motor was an old Winston Cup bench motor. I detuned it from 700 HP to 525(ish) for street use. You can't imagine what's inside that motor!

9K? Yeah, I'd love to know what's inside. That's serious RPM for a production based American V8! Even small block Chevy's seldom hit those numbers.

What I find surprising are the intake manifold and those headers, which to me suggest tuning for torque. They are beautiful, in any case!

Very cool ride!

As for the Countach? Who wants a car you absolutely could not see out of?
In reading up on it, I found this quote: "The layout is masterclass in how not to do ergonomics, and if you're in one of the later, chunkier seats with electric adjustments, it's actually worse. It's just something you'll get used to, and there are ways to make it easier, including (whisper it) aftermarket power assistance on the steering." LMAO!!!

It just looked like the Cheese-grater Transformer. That design suffered from some severe run-out.

I had to chuckle when I read "Even small block Chevy's seldom hit those numbers". There's nothing magical about a SB Chevy. In fact they have a few design weaknesses that hold them back:
1) The Siamese intake/exhaust ports which create unequal runner lengths
2) Distributor mounted on the rear of the cam which creates timing issues a high RPM
3) Small intake/exhaust ports. 351C has the same size exhaust valve as a 426 Hemi.
4) Large cam journals. 351C has smaller cam journals which reduce friction/heat at high RPM.
5) 351C has staggered valves

I won't get into the design features of the 351C. They are well documented on the web.

@Guildedagain, you're right.

The car is a prostreet car with box frame, tubs, narrowed 9", etc.

But did it have a bench front seat? :D
What kind of fuel do you need to run with that compression ratio?
(With apologies for the butt-inski): Don't think you can get better than 94 octane in US anymore, so I'm guessing octane booster? And excellent timing?

The Falcon was a "Sport Futura" which came with buckets and a center console. I designed the frame and tubs in such as way as to keep the back seat. I wanted the car to be a sleeper. It looked like a cool hotrod, not a 10 second 1/4 mile prostreet car.

Agreed, but they have been the poor man's race motor for many years.

That Cleveland is awesome, and that Falcon is definitely a class prostreeter! Well done, sir.
