Ok thanks for the replies.
Yes I am not as educated on trans. as engine stuff.
Ran 727 in my bracket car for 30+ years never an issue.
This car has an appetite for 3rd gear. I blamed in on tall gear,strong torq. and street abuse. I beat it like it owes me money.................
I shift at 4,800rpm at the track,trap at 5,000 11.0`s et. All bottom-mid power.

So the T/A RMVB`s have been the std when I started in the 80`s.
A 4 clutch high should handle that power just fine....right???

What about the driveshaft bottoming out? I have 3/4" free play. But what if its bending the front segment...just a theory.
It only goes low 11`s but from a roll with traction on the street,it is an animal shock. Bit of a pig at the track with 100% hook. If I took you for a ride up the valley,then you rode with me down the track you would ask whats wrong the the car BIG difference in performance. spank
Which is why I went with more gear.. work

Will check cooler flow and orfice stuff today.
