Does anyone have a Holley 4160 carb or a similar Holley 4 barrel? I'm looking to buy one and just seeing if someone has one sitting or has a lightly used one.

you are better off buying a 4150 650 or 750 depending on your build.

What manifold are you using?

I would go with 570
Street avenger if your engine is stock.

I ran a 650 double pumper on a stock 307 with headers all I had to do was change the pump cams .

I ran a 570 on my stockish 350, it ran great. Run a 670 after the rebuild. Runs great with minor adjustments. I am not saying you can't run bigger but 570 is plenty for a stock or mild 350. Most people run 750 on a 455.
