Magnum Cam Selection Suggestions

Could check out Hughes,Imm here,(Brian),Or Racer Brown has a nice grind. You're dead on the money,spec wise. Just assembled my own Iron Rams myself. With the Hughes 1110 springs and matching retainers. I considered. 530 lift safe. I measured .580 between bottom of retainer and top of valve guide seal. I used a HOWARD'S" retro-fit" LA hyd roller. 229/233@ .050,110 with a 106 intake center line. Forgot it was on a 1.5 ratio. Switched to a Chevy rocker setup. .520/.515 lift on a 1.5 rocker ratio.(oops!).Heads will peak at close to .525 lift anyway.
