I seem to have posted something that is still confusing?
I just went thru the whole thread looking for another Dan. (but he's "ph23v0" & hasn't chimed in, yet)

WHAT I KNOW:
1 - all 1970 "L"/E61 code 383s are 2bbl & are painted blue.
2 - all 1970 "N"/E63 code 383s are 4bbl.
3 - all 1970 4bbl 383s painted blue have a CARTER carb and a 330hp rating.
4 - all 1970 4bbl 383s painted orange have a HOLLEY carb and a 335hp rating.
5 - all 1970 4bbl 383s are NOT HP engines.

Any arguements/disagreements on the above 5 items?
