in looking for more power is a solid roller cam just that muhc better than a hydralic roller??? i was looking at two different 496 dyno test on superchevy.com and the 496 with a hydr. roller never got above 600hp but the solid roller was well above the 600 mark and pretty early??? the builds are very simliar except for a few differences like rockers, cam and slightly bigger bigger heads. so is a solid just that much better????
