340 issue after camshaft change

Can u explain to us exactly how u adjusted the preload? Did u pump up the lifters with oil? U got to be missing something. We want to help u!!! Kim

No, per comp cams instructions, pumping them up is not required. I understand the help and appreciate it. I’m convinced this camshaft is bad from the manufacturer. It is coming out. Like I posted earlier, I’m not putting any more time in troubleshooting it.
I’d appreciate some suggestions on a different street camshaft with a little lope to it. Thanks.
