Hylift Johnson Lifters Quality Decreasing?
I used Crower Cam Saver hydraulic lifters in my 340, and the quality and install was fine, as well as break in and the current performance, all on the old Purple cam that was in the engine when I got the car. The difference in oil pressure using cam savers is like 5 psi, which I had 50 to 60 psi before I yanked out lifers that were missing clips, now 45 to 55 psi with Crowers. I checked for a crown on the lifter face, lubed them up and dropped them in the bores, and then checked that they rotated and moved up and down in the bores smoothly before declaring them fine.
Also, every couple months there’s a new thread about bad lifters or what lifters to buy. The answer is buy wooden dowel rod the correct diameter and cut it to length to fit the lifter bores, it will probably be just as likely to work better than some of the shoddy new lifters available. Otherwise, buy your favorite gamble and be ready to run em.
