Making big time progress on my 1961 Cadillac Coupe DeVille because we finally have the Nelson Racing Engines 540ci twin-turbo big-block Chevrolet engine. We wasted no time in swinging the Dart engine block, Master Motorsports cylinder heads and NRE Alien intake maninold between the fenders of the Mac Daddy Caddy only to find out that fitting this thing under the stock hood is gonna be harder than it looks!
