Yep, Dennis is right. "Stall speeds" in reality are somewhat vague, and lack the precision we give them. They are "ratings", not scientific/exact preset limitations. A 3500 stall should deliver you the results somewhere between 3000 and 3500 actual RPMs. A 3000 stall between 2500 and 3000 RPM, and so on.

The factory OEM Marauder torque converter is a 2800 RPM stall, effective between 2555 and 3011 RPMs, as tested and published by Ford. Thus, an agreement of "2800", or, "higer" stall than other Ford passenger cars. Here's a breakdown of all of them.

4.6L 2V CV/GM, pre 2003 MY...2094 to 2440 RPM
4.6L 2V CV/PI, pre 2003 MY...2319-2750 RPM
4.6L 2V CV/GM, '03 and later...2031-2374 RPM
4.6L 2V CV/PI, '03 and later...2372-2808 RPM
4.6L 4V Mach I/Marauder, '03 and later...2555-3011 RPM.

If you look at the spread of effective stall, and consider the average "seat of the pants" g-force of these specific automobiles, the lower stalls tend to contribute to an immediate and very short feeling that the car is quicker off the line. I've driven a bunch of stock CVs and GMs from as far back as 1991, (5.0L engines, but lower power ratings) and I have had that feeling..."this car feels quick". But, for about 10 feet.

Higher stalls in the CV/PIs I have driven have felt sluggish in comparasion, but I used to attribute that to all the extra police equipment and drag forces present in a loaded police cruiser. But, a higher than average stall is partially responsible. When I got my first Marauder, it was really a slug off the line, until I learned to drive it differently, and later, to tune around the shortcomings. Once I did, all was well.

NOTE: When I came into this 411, I asked Ford engineer if all of these converters are the same 11.25" unit construction, and I got a "you have three eyes in your forehead" look before he said "well, the '04s got some upgraded bearings." F.Y.I...

Spool up a 3K or a 3500K stall and get ready for either hard acceleration or a cloud of tire smoke.

What did I just read? Stall speed? someone is going to tell me to do a search...i can feel it.
