I would like to know if anyone has an estimate on power gains from upgrades on a stock 5.0. I recently purchased a Cobra upper and lower manifold, 24lb injectors, BBK 24lb MAF, BBK 70mm TB from a local engine builder. I also have BBK ceramic LT into BBK offroad X-mid pipe backed with a magnaflow catback waiting to be installed. What gains should i see from these mods alone? Next year i plan to go with Twisted Wedge heads and a B303 cam. what power would i put down after the first mods and when complete, my goal is around 350hp, running mid to low 12s would this be possible?
