Re: Cam knowlege plz.
Ok, I stand partially corrected anyway...
70-72 400's some were 4 bolt mains. Also some only had the 2 core plugs, but all had the boss for the third. All had an external "bulge" around #1 cyl.
I still can't find any information that leads to a 4bbl carb.
Production dates.... 1970-1980 only.
