The 383-335 horse applications vary by year. What happened in 68 may or may not apply in 69 and may or may not apply in 70.
Any 69 B body (Charger, Satellite, Coronet) with a four speed and without A/C received the 335 horse assembly as there was no four speed 330 horse assembly in 69 as there was in 68.
Any 69 B body with A/C received the 330 horse assembly. Any non Road Runner or Super Bee with an automatic received the 330 horse assembly. This is verified via broadcast sheets and Lynch Road fender tags.
