Reg cab swb 2wd. My best time is a 15.1 at 9xmph but that was leaving on 0 boost and very worn 305/40/22's and doing a burnout for a good bit of it. It has traction bars now and just needs slicks. It is on the way right off I10 in Ms. I have no reason to think the trannywont hold upother than stock shafts and an unknown single disk. It runs well and doesn't slip or shudder though. Tim Barber is finishing my new tranny now.
