The fast, sleeper old Chevelle part I get just fine. What I don't get is the supposed 1400 hp part. And when I say, "supposed", I mean that I don't believe that it has exactly 3x the the power of a ~460hp V-8. Not for a second. Unless HP is somehow measured on a diminishing return type curve. What is the torque at what rpm for this motor? HP of course cannot be measured, only torque, and then HP is extrapolated from the torque figure. If this thing really has 1000+ lbs./ft. of measurable torque, I'm impressed.
What I'm not impressed by is that I'm sure it is only marginally quicker, if at all, then a well set-up 4-500 HP '64 Chevelle from 0-60 or in the 1/4 mile. It has monstrous torque that can spin the tires at any time, (whopee!), big deal in the real world of performance driving. Excess power is like taking a whole bottle of vitamin C every day, only the amount you can use does anything. The rest you piss out, or use to ruin your tires in suburbia in this case.
