My friend builds engines and he won’t use anything but those. He has been buying new old stock cams just for the lifters because they were made in the USA and good quality. Lots of stock lifters are also good as long as they are made here. The stuff from China is garbage, don’t use those lifters, the cams are OK it’s the lifters that are causing problems.
I just had another buddy install a new comp cams kit in his new 440 and the lifters wiped out on the dyno, He used the lifters that came with the cam and they are junk, this was about a month ago. Now he hast to spend way more than $300 to fix his engine...He’s not the only one this has been happening to either.
