Fishy68,
You didn't offend me. Not at all, LOL. And I didn't take it like you were disputing my comments. And I surely hope I didn't offend you. I enjoy a good tech session with my Mopar family. I surely don't know it all. And I hope it doesn't come out like that. The sheet you posted is also on Moparts in the archive section. I am sure that is were you saw that. I wouldn't hesitate to use any of the different LA castings if I had them. That is really what I was trying to say. This was a good topic. I enjoyed it, thanks guys. Now,..next topic. Why did Mother mopar use those 'tulip' shaped intake valves anyway ? LOL.
Terry.
