Restoration 273

hi, I use to run 273 motors , the iskenderian brand of cams offers a very nice solid lifter cam for the 273 motor, grind is the E 4. it works very well in the 273, you will not have to change pushrods. you should upgrade the rocker arms with the mopar newer nut and bolt kit. the E4cam specs are; 260 dur/216dur @.050, 108 LCA, .425 lift, .015 lash. I have used this cam in 273 before, it wakes them up. very driveable, has very strong low end and mid range torque. can be used with a stock convertor. go with mopar ignition or MSD. A 500 CFM carb is more than enough for this motor.
