So, working on my 572 Hemi, 727 trans mounted in there with a front engine plate and a mid plate between the engine/trans Challenger yesterday. It has been so long I am unsure of the source of some of the parts, and I noticed the converter when pushed all the way into the trans had a much larger gap then I am accustomed to so I measured and it was about 3/8 of an inch. I cannot recall if my converter setup is indeed intended for a car with a mid plate so that seems wrong to me? On the other hand if I took the mid plate out the converter would be literally touching the flex plate...

Can someone enlighten me on the proper gap? Is 3/8 ok or will I be too far out of the pump drive when I pull it forward and bolt it up? If it is too far, how do I correct it?

You might want to post this in the race section I think your good, most of the aftermarket race converters(10 to 15) I've used had more travel than yours does. That was with no midplate
