Best Cam for a 340

Well when I read a thread I begin at post #1.
And I like to offer enough information in my first post for a guy to not have to come back in 20 minutes and ask for more help. Sometimes I don't get back to the thread for a few hours or days, and the poor guy might be left hanging.
I also like to offer insights as to what has worked for me. Or hasn't.
But if you all think I'm being wordy, I'll try to keep it shorter.
