If you win the hemi tick lotto, you would understand and you would follow the work that was done here, this I promise you. Until then and hopefully that day never comes, you get to be "critical". But the more you read this forum, the more you will see for most guys this is the only answer. Even replacing cam and lifters is hit or miss if it corrects tick. So you are right, literally it would take an engine change for the best shot at it, however then you still have a hemi and hemi's are all susceptible to it. Hemi ownership becomes a quagmire and a riddle Wrapped in a Mystery Inside an Enigma when that engine starts ticking, the easiest fix, try a lubrication strategy. Unless you like hearing your truck knocking, then by all means just ignore it, we have a group of those guys too, wear it like a badge of honor.
My hemi tick started at 3500 miles new and according to dealer is normal, should I have bought a new engine? I wish I had that money.
