Shout out to Howard’s Cams

I used the same lifters with one of their cams in a stock 340 a little over 2 years ago. I didn't disassemble the lifters. The engine was running great before the change so I made sure everything went back together exactly the same. Break-in went smoothly and I have since put on about 5,000 trouble free miles. The lifters do bleed down so they clatter until oil pressure builds.
