This is true.Didn't mp used to have a bearing that pressed into the torque converter pilot hole in the crank. Then you can simply drill the crank oversized for input shaft pilot. No precision required.
Fyi the 440 cast crank is a cast steel crank not a cast iron.
.Not all of them are. There are many 440 blocks from later years installed in trucks and motor homes with cast cranks, and they are all as viable to build, if not more so due to casting improvements, than an RB block from the earlier years.
My 440 is reportedly out of a RV (crammed it in a 73 Duster). The damper that came on the engine is the same as the 2nd photo down (#3614371) on this website Harmonic Dampers 440 Source.com and the counter weights on the crankshaft are rounded as can be seen in this photo. This photo was taken when I first opened up it up after who knows of how many years.Yes, you can remove the weights. I'm surprised to hear your crankshaft is forged steel being a 73. 440'
.I have a '73 440 forged crankshaft with the correct balancer. About a year ago my mechanic friend rebuilt my 727 transmission & ordered a new torque converter. There's been engine vibration when throttle above idle, did the research, not supposed to have the 2 weights and plug since it's NOT a cast steel crankshaft so I rotated the torque converter and sure enough it has the weights and plug. It is ok to grind these weights and plug off vs buying a new TC without the weights?
