I remember seeing this video years ago and not believing the #s. There is another video of his "peter willie" Cuda on Youtube and i saw a few 156 and then a 157+ MPH passes. This was supposed to be a 'lesser' HP version of this motor, and in context, I think it's believable. At least in the ways I correlate HP to track performance. I'd WAG this Cuda has to be at least 3200lbs with driver?
Peter's Cuda has a chassis that is legal for Super Stock, it just needs a Shaker hood, instead of the 6 Pack scoop. It's probably closer to 3400lbs, with driver.
