also I thought while I do have both a stock 22re and a "upgraded" 22re in a different truck I might as well share the differences that I experience. so far the "upgraded" 22re has a street rv head and a 268 cam from eb. The stock 22re is in a 87 extended cab 4x4 manual tranny 31's and the "upgraded" is in a 89 4runner 4x4 manual tranny 31's. so far the 4runner is a faster drive. It gets up and goes. It feels like a sports car compared to the truck. It doesn't have the top on right now. And the speedo dosn't work so no gas milages to compare. But i'll keep you updated if you like. if not in this tread then in my "project build" <img src="/forums/images/graemlins/lol.gif" alt="" />
