Yeah, it is a possibility. Do you have another reason why you would need to use so much jet/pump shot?

And it needs larger than normal jets to accomplish it. Why?

Since the Q-jet mixtures were not changed in the same manner as the Holley, it could easily be 2 tenths slower. Not because it was inferior, but because it was jetted too lean for that application.

Here it is, again.

It was a question, not an attack.


RE: The original question:

At this power level, there should be no difference in ¼ mile times/speeds between a Q-Jet and an equal size Holley.

The clear advantage the Q-Jet has over the Holley, or AFB, is in its efficiency at under 2500 RPM cruising speeds. At WOT, you should not see any difference.
