What ACTUALLY happens when you floor a Vacuum Secondary Holley. This is on the 360 in my Van. Thank the Van :)

It almost appears that it may need a lighter sprAng. If you think about that, I would get one of those infinitely adjustable secondary pods like from quick fuel. You could really zero in on it then.

Like dis rat cheer.

One thing I do love about working on a van is the engine is right there after the doghouse is removed. With the weight of the van and the rear gearing we had to put a stiffer spring in to keep the 600 carb from bogging. The stock silver spring was too weak, so think we went to the brown. Good stuff!
