I'm on the hunt for more power I can't stand having my old srt4 run a faster 1/4 mile time. Car is a 2013 m6 3.31 I know there are a lot of tvs vs nitrous threads so don't flame me lol. Anyways just looking for some advice or experience with higher mileage 5.0s. I plan on a built engine eventually just want to keep the stock block as long as possible.
