Thank you Mike. Interestingly I used your site quite a bit when I was researching some cars. I almost bought a 400 car and found your detail on that car really useful.

I couldn't find it listed on your site. I have seen the engine production #'s by engine code.

Would you share the Simmonds sheets as well as the numbers for automatic vs. manual transmission. I have not seen this yet and it may help as I narrow things down.
