Glen - sounds like you know your stuff. Please advise me on following:
I have a new GM crate HO with Edelbrock Hi rise RPM endura - was running a 1406 out of the box with no problem - changed carb "only" to out of the box Edl 18064 Thunder for "endurashine Purposes" - It fell on its face when hitting WOT before 2500rpm (after adjusting per Edlelbrock for fuel pump stroke and AVS and various settings) -sent carb back and dealer replaced - in meantime put on an old Holley I had - then adjusted and it screamed No Problem. Couple of weeks later and I installed the replacement out of the box factory 18064 and I have the same problem again. Love the LOOK but want it to run right too. Any Suggestions?
