Billet alum heads, titanium crank and rods, "custom" block. They have their own in house chassis dyno. I dont doubt their around that mark. If we can make 1400+ with a little 359 ci. twin staged turbo, six cylinder, still running farm fuel and olde tyme technology. Then it's feasable with a 640 ci. quad two staged alky injected V8 with cutting edge technology and an unlimited budget, and a whole fleet of eager customers for your test bed.
