Holley 4 Barrel Carburetor taken out of a truck that was running. This item is being listed as-is, will possibly need a rebuild but was taken out of a running vehicle before replaced with a smaller carb. This was once used for a truck racing team and became part of my daily driver 74 Ford truck. I have another listing for a carb spacer that was used with this carb. 

This carburetor was working great when taken out of a running vehicle but I must list it as-is based on not being able to be tested and I am not a mechanic or know what components would need to be tested. I am listing it based on the information I have so I am not 100% sure which specific model this is.
