I'm sure those engines balanced horribly from the factory but they did it. All 440's had the pilot hole in the back. It was a two step process. They all had a rough pilot hole, but ones that were destined for a stick shift were bored out and drilled a little deeper.

Auto truck had a 400,727 and a D60 front axle. This was a 1978 vintage Stick trucks, one was 400, one was 440. One was 78 one was 77. Why did these HD trucks get a steel crank? Not sure, but if I had to guess, Mopar was getting out of the big block business, so perhaps they were using left over replacement cranks or parts from Direct Connnection, to use up stock or fill needed orders. I used to care but....... things have changed

I've seen a few steel crank 440's right up to '78. I had a '76 400 with a .010/.010 steel crank. Has a maltese cross on the pad so that's the way it came from the factory. Also big '73-4 motorhomes seem to always have a 440-3 with a steel crank, six pak rods and internal balance since the low comp pistons were lighter.

They didn't have to dissassemble the crank either. Might save you from having to sell your current engine. live every 24 hour block of time like it's your last day on earth
