Tom, What are you running for a Torque converter? What's the stall? A number of years ago, I was making a number of changes to my combo. Each change involved making more Power and torque. With each change, I had the same Torque converter reconfigured. The changes always lowered my ET and picked up MPH however, my 60ft more or less stayed the same. I finally installed a playback tach and discovered that the converter was locking up early, then unloading and stalling where it was suppose to. I bit the bullet and bought a ATI fuel and blown converter. The car picked up 2 tenths and 3 MPH. The 60ft went from mid to low 1.40's to low 1.30's and high 1.20's. My car weighs about 3700lbs with me in it. My best 60ft is 1.25 with the 572. Given what my car does on the bottom, there has to be more left in yours. Just food for thought! What do you think? Jim T.
