Holley's products include carburetors, fuel pumps ...The stock jet sizes should be a #45 slow jet, and #190 main. Dont know if this helps you or not, but I ended up re-jetting with a #50 slow, and a #195 main. I tried several slow and main jet sizes before I ended up with this combination. I also have Cycle Shack slip-on's, and an Arlen Ness big sucker air cleaner.
