I have an older Holley 4160. It's a 3310. Not a 3310 anything, just a plain old 3310. The carb is the old 3878261-EH. When looking at the Holley chart, it does not list a renew kit for the application. If it were a 3310-1 and I have a feeling that it's how they listed it, says to use a 37-1539 kit to rebuild. This kit is over $100. If this was any other 3310-x, it uses a 37-754 kit which is $30. Any ideas?
