A few yours back a friend bought a 451 kit from Muscle Motors and the 440 crankshaft wasn't drilled but was spot faced, was the first one we had ever seen and I posted it on Moparts but was 15 years ago. Glad you confirmed and is good that its neutral balance
I got an Eagle 4.15 crank in my 493 that isn't drilled for the pilot and I'm a stick shift guy
