318 Rebuild suggestions?

Yes on the cam... my 351C would get 18.5-19 mpg all day long at 65-70 mph (3.08 rear axle and stock non-locking TC) and yet make 350-375 ftlbs torque and 325-ish HP. It used a 70's Crane HE series cam.... 'hydraulic efficiency'.... generated when the Arab oil embargo hit. It had narrow .050" durations, but pretty wide .005" numbers to be able to use in a higher SCR engine to keep DCR from getting too high, and wide LSA (114*), and high lift. So slow ramps at first and then steep ramps around the peak of the lobe.
