Noisy Valve train on new motor?

Some Hr's cams can run solid rollers w tight lash. Call the cam mfg and find out. You may be able to switch over.

Thanks for the suggestion I’m going to see if that’s a possibility.

Just a suggestion, Would banana cuts on the shaft help that out? I put them on my Crane aluminum rockers and they are quiet. The 340 T/A were like that

I had the same problem with my engine. A friend that used to post on FBBO a lot told me, These aren’t Chevys, you need more lifter preload, 1 to 1 1/2 turns. Set mine at 1 1/4 turn, most of the noise went away and seems to run better. I still have the fast ramp chatter, but the ticking went away.

Prnd21 was correct. I called crane with my part number and they are a full travel lifter with a pre load spec of .080. 1 1/8 to 1 1/4. I was setting them to Harland sharps instructions. My ticking is gone I still have ramp noise but with extreme energy cam there is no getting away from some noise. Thanks everyone for your input
