Thanks for the replies. This transmission is going behind a roller cam, 572" Hemi.

There is more to it than just line pressure, the entire trans build and valve body comes into play. For that big motor and heavy vehicle, I would want a valve body designed for at least 120 psi, and prefer 5 clutches in the front drum. Just my opinion. I don't know what valve body you have, but it sounds like a modified stock one. Call John at CRT and order one of his valve bodies.

If you really want to experiment, he might sell you one of his regulator springs.
