I two matched 390cfm Holley carbs. Professionally rebuilt by Steve Zepeda of Zepeda Carborators, a renown carb specialist in Houston. They have not been reinstalled or had any gas through them sence rebuilt.
Carbs still in the package with the rebuild tag. Replaced parts were returned and are shown in the plastic bags )(behind carbs). They were on a 429 boss. EMAIL me for bigger pic. email@example.com
PS. Question: Why do 90% of e the street guys over carborate?
