I now have the cam I have been looking for. Cody at Gambles High Performance Machine, hooked me up with one of his billet cores . A few weeks later my cam showed up, here it is solid flat tappet with lifters. Int. Exh. Duration @ .050 , 244 / 254 , lobe lift, .346 / .333 with 1.5 rockers , .536 / .516 I have 1.6 rockers. on a 104 int. center line , 108 lobe separation I think this will work very good with my ported E-heads. Thanks Cody !
