I am in the process of rebuilding my engine for my Everett Morrison AC Cobra. After looking at my ford original cast iron engine block, it has the side bolts for the mains, screwed in large freeze plugs, and next to the water pump on the upper right had side it is stamped 352. From what I have read about this block, no hydraulic cams can be used on this block. So am I correct in assuming a hydraulic roller is out of the question?
