Money... It can get you things... such as a SBC that displaces more than 400 cubes and 695 HP and 615 ft lbs of torque.
All for the petty sum of 25 grand.
Imagine the GP you could have for that?
I could buy a **** condition 80's f body and upgrade the suspension, engine, interior for less than that.
I think 500 horse is about the limit for street sensible

7 grand less for 640 horse instead of 695, and you'd be running a carb then.
