      My husband used this to replace the "stock" one that comes in most Holley rebuild kits (the 135-4).Fit perfectly into his Holley 1848 465cfm

      This kit works great for tuning the vacuum secondary opening timing. If used with Holley 20-59 quick change housing it's a breeze to swap out springs. Don't let the picture fool you, there's seven springs in the kit.

      Great to have on hand to dial in the secondaries. comes with instructions and suggestions for spring selections.easier to use if your carb has the quick change secondary spring kit.
