Ok, i'm going to be installing a lockup 904/998/999 into my Dart pretty soon, and I have 2 converters to choose from, and want to know what stall they would be. I have a factory High Stall lock up from an early 80's 904-LU, and an un-marked converter that came from a late 80's/early 90's B250 fleet van with an injected 3.9L V-6. which one would be higher, and is there any way to identify the van converter?

Thanks
JJ
