I was putting my truck together when I ran across this problem. The old converter was for a 440 and I'm using a 400 now. I took the 400 tq and all, but it doesn't fit my trans.. The fork that goes in to the tranny are bigger with 400 than the one for the 440.
I was just going to use the 440tq with 400 engine, but it looks like the 440 tq has two weights by the tq drain. what will work...
Thanks MIke
