I think it will run out of high side on that setup with e60. Many guys are ok letting high side slip a few hundred psi, but once it start falling 3-400 it gets in trouble quick. The upgraded high side does very little on a lt4 car. Run it on pump and ease the ethanol in and watch the high side fuel pressure close. Low side and injector is solid. I would trim the E content back until you do a camshaft.
