I saw that kit during my search and every time it popped up the application was listed as:

Torque Converter Balance Weight & Positioning Template Kit
Fits Most 1971-'79 383/440 (with cast crank)
Fits 1971-'92 360
Fits 1971-'76 340 (with cast crank)

There is no mention of the '70 heavy rod steel crank 440. Do you have a copy of the instructions or some other documentation that indicates this kit has this coverage? Appreciate the help.

6PakBee here is a link to the Mopar performance catalogue. Go to the auto trans section and look at the torque converter application chart page 91. There they tell you to use the weight kit P4120241 with the 440 six pack with heavy rods.
