Message: I bought a 5.2L today to swap with my 3.9L. Won't have time to do it until December though. Anybody know where's the cheapest place to get headers? What kind of exhaust set-up should I go with (should I still stick with cat-backs or go with true duals?) What kind of mods can you guys recommend? Should I swap to a larger radiator for the V8? I'm gonna research but I just want to get a jump start on this.
