it's not a stock 360 it's a magnum, magnum head works really well, the 380hp create is a stock long block, with 230 cam 4bbl headers is a known low 12 even high 11 if setup right. Few that been dyno made over 400 hp, even with a mild 210 cam made 350-360 hp stock cam around 300 hp. An LA 360 is gonna need more cam to hit 300-360 hp and headed work to get over 400 hp. Why a lot suggests grabbing a running magnum add 4 bbl cam headers for cheap bang for the buck kind of our 4.8/5.3 LS just not as good :)
