Tunnel ram or no tunnel ram...

No PVs in carbs. I have a bit lean cruise at mid to high 14 but no surging or anything. Seems happy, goes richer when secondaries kick in and they do kick in quite fast. There is linkage progression but very small comparing to my previous carb. I will play with jetting today and see where I end up.

IMO, if you are going to drive this on the street it NEEDS power valves on the primary side. Those who say otherwise do not grasp what that valve does.

Install power valves and you can drop the primary main jets at least 6-8 numbers. Then tune from there. You‘ll never get your cruise A/F ratio close without power valves.

I swear that Holley has done more damage to that carb and how it works and tunes than anyone else. They STILL have videos, books, YouTube advice on how to incorrectly time the power valve circuit. It’s idiotic.
