Looks to me like you are not reading Dan's posts.They are not confusing.An L Code car is a 2bbl ...not a 4 bbl.Galens production figures are taken from the 1970 SG 30's...an option and accesories report printed every year that breaks down all the options by percentage points.As stated ..the N code cars could have either the 330 or 335 horse 4 bbl engine....the SG30's do not differentiate between the two.I've seen 3 N code converts come up for sale in the last 3 years...only one had AC,one had the 335 horse eng with the 355 perf axle package and one had no fender tag.The actual production figure for these cars is probably closer to 50 as the 36 figure is for US cars only....does not include Canadian cars or Export Cars.
