What is a good stall to go with a 3:23 Sure Grip?

i share the sentiment upthread in that's a whole bunch of bumpstick for 3.23's

that thing is gonna want 3.55's minimum and a fair amount of stall or it's gonna be dogwater downtown till it wakes up in the upper mid.
If it was mine, it'd get a tight converter that'd flash to 4200 with 4.10s, but I was tryin to be conservative. I wouldn't be conservative for "me". LOL
