2700 Ito the 360 and it has 380 hp ? My 340 makes 413 hp 398 tq built to stock specs . All that was done was a bit of cleaning up the heads ,new stock spec pistons and a mild cam . So the op can have a 400hp 340 without putting in the money he would need to get the 360 to 400hp . How can spending close to 3 grand to make less hp and tq be advised ?
