My 904 pulled from a 318 question

The weirdest thing for me was I got that 360 and 727 combo that had been rebuilt. The one that I put in the Power Wagon and drove to Colorado. When I had it apart it had no weights on it? That's when I went to my 360 torque converter for an old car that had and chiseled the weights off and Welded them on.
The guy said he bought the truck as a complete rust bucket and drove it home and felt it had a cam in it? I think it was just shaking from the missbalanced torque converter.
LOL.. he was right! An instant, cheap, rough idle cam if you have a 360: Chisel the weights off the converter … LOL :D

Question: why didn't you just put your converter in it? Save the chisel and weld job.
