318 LA cam question for the mopar gear heads!

Guys I really appreciate all the good info, I'm not a very good auto mechanic, but eager to learn. I'm a multicraft maintenance technician in a industrial plant and a electrician by trade. Thanks for all the good info and its great to be able to use this forum to pick your brains. Y'all got me to thinking that I may want to take it a little further on the rebuild!
