You have a Model Number 4160. The Part number (p/n) is 1850-4. The Holley renew kit is p/n 37-119.

It came w/66 jets in the primary side, the secondary side is metered through a "plate" not jets like a 4150-type carb uses.

The power valve is a p/n 125-65. Some repair kits include the power valve, others might not. If you get a kit for your carb that does not contain a power valve, ask for a "#65 Holley power valve".

An exploded view of your carb is HERE.
