In 58' all engines were drilled for hydraulics. Therefore if your 55' had a standard tansmission as most did then you should continue the cam and lifters that it came with. I would point out however that in no circumstance should you put lifters from another engine with another cam. Lifters and cams should be replaced as a set. | | |
