I've seen it on a Hemi my builder did. His customer swapped the 440 in his 70 RR for the Hemi and used the trans and converter that was in the car. It wiped out the thrust on the Hemi in short order. The 440 thrust was OK.

The Hemi was built with the stock crank and just basically warmed up a little.

According to my trans shop you can run a Hemi core converter behind a wedge but you can't run a wedge converter core behind a Hemi. He said the register sizes are different. Hemi is smaller.

I have never measured to confirm this.

In any case a new converter and thrust bearing in the Hemi and all is well.
