Being new to ls engines, everyone has to start somewhere, so I set a rather low goal of around 350hp. Right now I am sitting bone stock as far as engine and trans goes. Is my goal reachable without going to far into the engine? What are my options? My pockets aren't deep enough nor is my spare time abundant enough to lq4/lq9 swap, so I'm planning staying 5.3 atleast till I blow something up. So how can I hit my goal without breaking the bank? Is 350hp even plausible without a cam and major internal work? How about a more plausible number?
