ok so I know generally how a torque converter works, but what exactly changes when you change stall speeds? does the car drive differently? how exactly? I like the way my car drives now, but Ive been told that i need a torque converter before I do a head/cam swap. thanks

With a verter, your normal acceleration will be "loose", like you need to give it more gas to start moving. It almost sounds like a manual taking off, if that helps you picture it

I just got mine installed two days ago, and it's very nice I went with a 3800, and it behaves very nicely for a daily driver. I can join everyone else now, when I say that I HIGHLY recommend a 'verter

Yes it will feel looser meaning more gas to get going and you will spin more RPM's untill you reach lock up speed (about 40mph) then it will feel like normal. It will eliminate the "dead spots" we have (when it down shifts and you hit the bottom of a gear) because the verter will unlock and flash up to it's stall speed and keep you up in the power band and you will get better shift extension on up shifts (RPM's won't drop as much during shifts keeping you in the power band)

gets you in the powerband quicker from a roll and you can launch at much higher rpms...must mod for an auto
