Well depends on what yu are building ,,, a good stout street engine or full on strip/street, i went with the forged root, because i scored a good deal with my engine rebuild shop .....H beam will handle more hp that i beam .. forged is a very good way to go if yu are planning or build a stout motor with impressive hp and torque,,,.so some where down the road i do plan on procharger .....so since i do plan on blower i might as well built a good stout bottom end ,,,,,it all depends on how much yu spend or what yu want to build.So build it strong with good parts the first time and yu won`t kick yur own ass for not making it a strong almost bullit-proof bottom-end ,,,, Like my Wifey told me " Its only money, so spend what yu want"
