Can anyone tell me what is different about the 1956 322 push rods? Are they longer or shorter than the 1955 push rods? Has anyone used the adjustable push rods sold thru TA performance? I am going to remove engine when I replace the dynafow with a 700R4 and relace a ticking lifter. I plan on relacing all lifters. It unloads when car has sat for a week and build up after a short idle period. My last lifters cam from (Camcraft )I don't know the manufacturer. Which are the best lifters and manufacturer? I only want to do this once. I have also used an aditive in the oil since the engine overhaul.
