Hey guys I have a 1963 327 engine, we just rebuilt. The engine had very low miles, but was sitting for like 30 yrs. All we did was rings, brgs, (hydraulic) cam and lifters, oil pump and valve springs. The oil pump is an M55A. I have 60lbs of oil pressure on the guage, (its a mechanical guage) while priming the pump with a drill and the drill is laboring, so the guage seems to be fairly accurate. The problem, is that I can't get any oil to the rockers, no matter how long I run the drill, In fact their isn't a single rocker arm getting oil. I cleaned all the pushrods and blew compressed air through each one. Any suggestions, HELP.
Thanks in advance.
