Pull the plugs, put some
oil or Dexron II in and try turning it over by hand first. Don't put the plugs back in. Just try by hand to see if it is seized. For sure, drop the
oil, filter, gas and coolant!

"The 427 Cobra is easily the highest performance car ever sold for street use. A decent 427 - not the worst, not the best, will go from zero to 100 mph and back down again to zero in less than 14 seconds. All thing considered, you can put together a pretty good argument that the 427 Cobra is the ultimate performance car, judged on any basis you want to name." Taken from; Corvette, The Sensuous American
