Comparing a 383 to a 440 is like comparing a 396/325 to a 427/425. Different motors, different intakes, different carbs. Some 383's used a Holley. The 440's used a Carter AFB. Hood pins (code J45) were an option on the 70 Chargers. If the car had PDB it would be coded B41 for disc and B51 for power assist on the broadcast sheet but not necessarily on the fender tag (My car has "B51" listed on the tag but it is a Super Track Pac car which included the B41 Disc brakes with the 4.10 gears). Either way, power
4-wheel drums sounds fishy to me. Should be manual drums or power front disc with rear drums. If it is an original 4 speed car it should also have a Dana rear. If you PM or email me the fender tag or broadcast sheet I can be tell you what the car is/was/should be. -NJSteve
