Lead on a 408. Should I do it?

My impression is that he hasn't worked on it. Not real sure though. That is why I am going by there Monday. He was busy when I called him so ran through it quick

As for the drive train I was planning on beefing up my 904 at the recommendations of members here over the 727 I have. I am also looking at doing the 8.8 conversion. Not sure if that will hold up to a stroker.
