Stock Stall speed for the 4R70W transmission.
I thought since there's some misconception on what's a good stall speed to buy, I'd post up what the stock stall speed are for some common Ford cars. That way if you've even ridden or driven one, you can see that you shouldn't fear the stall converter. Your stock stall with fall in between the min and max numbers somewhere.
98-up Mustang GT....Minimum Stall speed-2324..... Max Stall Speed-2737
'98-up Crown Vic....Minimum Stall speed-2024...Max Stall Speed-2440

'03 Marauder/03-04 Mach 1...Minimum Stall speed-2555...Max Stall Speed-3011
Thanks goes to Johnny Langton for the numbers. If you don't know who Johnny is, you're a newb to the 4.6 world...... He was the 1st guy to get an NPI engine into the 12's naturally aspirated.....And that NPI engine was in a 4000lb Thunderbird. He's the guy the NPI guys have to thank for figuring out PI cams in the NPI heads, figuring out that the PI intake would work on the NPI heads with just some silicone, and figured out what it took to put cams larger than .550 lift into the NPI heads, 1st to figure out that ported NPI heads actually flowed better than ported PI heads. If it wasn't for him, there would probably be no fast NPI cars. And he did all of this in a Thunderbird.
