Car Jerks, Sluggish Tach Jumps And It Has a Code 56

Just recently I put a new dizzy in my car. I noticed that all the power was not there. Around 2k under load it jerks and the tach jumps. feels like a misfire. New msd wires autolite plugs all under a year old. Also a mild can. Timing is set to 14°

Last time mine did that, I replaced the TFI module on the distributor and fixed the problem. Almost has the feel of a slipping clutch. Also, if the back of the module was not lubricated with the proper grease before Installing, that too will cause the car to jerk bad
