yeah, thats a resto-mod tach behind the OEM bezel. you have to do that with electronic ignition as the pancake signal box wont work, at least not with with MSD. plus the factory tach was a 6000RPM snoozer, you could bounce the needle revving it hard. 318 is no slouch in that car with 'S' cam and LD4B intake, but you could do better than the factory S cam as its designed around a higher compression.
