I’m running a Holley 650dp. No vent tube extensions and the spectre hat. After the hanger18 mod I ended using a 6.5 pwrvalve and up opening the pvr from a 60 to a 90 as well as the icr from a 35 to a 53. I have rear PV blocked. 72 front jets and 78 rear. Cheap 044 Bosch pump with -6 feed, return aeromotive boost reference FPR. I can flood it out to a 10.0afr at 10psi with a 2 sizes bigger jet change in rear. Wondering if you have some trash in one of the circuits. You should be swimming in fuel.
