I'm almost certain they do, I had a running conversation on 'fritter, back in the day, with a notorious DuoHacker about the source of his QFP G3 collection. IIRC it was a boxy green assembly for something not Macintosh related and it was an iffy proposition to strike QFP Gold or just wind up with another fetid BGA POS in your hands.

Based on searches of the Applefritter forum I think you may be confusing MadDog's statements about fast QFP 603e CPUs as applying to G3s. From this thread:

f you are looking for QFP 603 CPUs, you can find 117 MHz parts on the 1400 cards, and the top end 5300. Otherwise, the best place to find fast parts (180 Mhz) is some powerbase CPU cards and some Umax C500/C600 CPU cards. note that some of the 180 Mhz parts are QFP and some are BGA. Make sure to ask before you buy. I have 2-3 180 MHz parts on CPU cards here, and I need to find a professional shop to do the work.

In another thread MadDog stated he didn't believe that even the more-modern 603ev came in QFP packages. Thus I'm still faceplanting on the effort to find evidence that QFP 740s exist. (If you look at *all* of MadDog's postings he never even mentions the 740.)
