you can add a hardened washer to shim the spring a bit for a few added psi along with a bigger check ball. did that on my 400/467 stroker, using 10/30 oil i get 70-80 psi at "cold" 75-80f start up, then a solid 25 hot idle. more is not better in this type of situation.

What if a guy is spinning to 7000 rpm? I run a 60 psi pump to 7000 rpm. It puts out 65 psi at that rpm. Thoughts? Thanks
No issues so far. 20w-50 Amsoil.
