It is targeting 2900 psi because I was originally running a full lt4 system but was advised to switch back to LT1 to see if it reduced fueling. Still running lt4 injectors which requires the 2900psi.
Both setups have had a lashcap with limited preload and do not bottom out on top stroke. It is the .060" lash cap slightly machined.
