Who do you use for custom torque converter?

I'm running a 3000 rpm stall, Precision of New Hampton lock-up converter in mine. Gave them my specs, and they nailed it.

Injected 408" stroker with a hyd-roller cam in an a-body turning a 4 speed overdrive auto, 3.91 gears and 265-60/15's.

Ask for Milt. He's one of their techs. Great service and great company to do business with.
