Hi guys-

I'm going to rebuild my 10R60 with a SunCoast Category 3 kit. I figure I might as well replace the torque converter since the trans will be removed and it makes sense to replace it then. I have no clue about choosing the torque converter stall speed & am hopeful to get a bit of advice.

My goal is the quickest quarter mile as I will never, ever get near the top end speed of my ST. Going that fast will probably just scare the crap put of me. I plan on replacing the spark plugs and beefing up the turbos, fuel pump, & injectors this summer. I'm also running on E-50 on a ZFG tune.

So, what stall speed would you choose for a category 3 rebuild kit? Keeping in mind I'm interested in being quick off the line and don't care much about top end speed.

Thanks in advance!

Curious also to see what the optimal stall speed is. @ZFGracing would know, and RSA would be able to tell you also.
