that sounds like a sweet set up red chevy girl...welcome to marlin..and to answer your question
i helped build a toyota in high school that had a blown 327(about500hp) a turbo 400, mated to dual toy cases, 21 spliners at that.
i personally whitnesed four whell burnouts (38 inch tsls), jumping of the truck, and 135 mph freeway sprints...that was in 1998, they are still going strong..no rebuiulds or problems to speak of
rock the toy cases!!! but do a 23 spline just to be safe
