I run an old TPI 8" unit in mine. Like the rest of the guys have already said, don't cheap out on a converter. There is a difference; I found this out several years ago when I replaced an el-cheapo vega converter that I had bought just to get the manual-to auto trans swap done in my truck with a TCI street fighter that had the same stall speed. It picked up 4 tenths in the 1/8 with no other changes.
