Magnum Cam recommendation
Call Oregon Cams. They have a consummate list of hydraulic roller profiles. Call for a recommendation, bet they can cam you for 150.00-175.00 on a quality regrind. (A new one is 300-400.00..) Hughes 1110 spring set ,and matching combo will get you there . Keep lift .500-.520" with a 1.6 factory rocker ratio. Have an idea of rear tire size ,what rear gears you want to use ,and stall speed converter.

Something in 220-224 @ .050 lift on intake, small split on exhaust. Pretty close to most successful Magnum builds here.
