I used to know what the hell these numbers meant but... on the front of the valve covers.... there was a number on the front of the valve covers... driver's side was either an "O" or something else... showing if it was a 4-speed or an automatic.... what was on the passenger's side ???
I have a 1970 Charger R/T with AC and an automatic.... so what should have been on the valve covers ?
on my car, a 69 R/T the number is 916 which is the last 3 digits of the engine part #. this number appears on line 3 of my broadcast sheet under the engine code. my car didn't have any # visible on drivers side valve cover, don't know if it ever was there.
hmmmmm thanks man... been looking through alot of old articles i have... passenger side valve cover got the last 3 digits of the engine build sheet code... driver was either "O" for a 4-speed and "125" for a kickdown linkage.
