Since my car is completely original I went with the stock lift and duration and bought it from Crane. I had what I thought was a bad lifter but once I took it apart I found that the rockers were also a problem so they were replaced also. Originally I started with just a lifter change but didn't like the way 2 of the lifter bottoms looked so I replaced the cam also.
I went with original flat tappet and used Rotella Oil with a can of EOS I had stashed. Also used the Crane stuff on the lifter bottoms and the lobes of the cam. No problems and she runs great.
The car still has the original mufflers and the baffles are shot so the next project is to replace the mufflers. Mostly everything on the car is original so I hate to replace anything.
