There's quite a few 11" converters in stock in my area.
Summit has a Heavy Duty 11" Hughes 2500 stall.

I had a 10" nitrous converter years ago that would literally bog down a 432" motor without nitrous, that thing was super tight. I just want something that doesn't quite feel as mushy on the highway as my good 9.5 converter and highway gears. My 9.5 would be a great converter for a 9 or 10 second street/strip car with 3.73 gears or more.
