1970 Charger R/T Questions

[rickp]

My partner and I, recently aquired a 1970 440 R/T 4sp. car. The car has a 750 Holley carb which I assume is incorrect (E86 code engine), but yesterday at a car show I saw a 1970 "383" Road Runner - 4sp. car, which had a 650 Holley, that the owner was sure is correct. I'm not a Mopar expert, but I believe both cars came with Carter AVS carbs. Another question I have is our Charger has power drum brakes and the code B51 on the trim tag, which according to info I have equates to power assist disc brakes. One last thing, this car has hood pins which I also do not think it came with, but I noticed the Banna Yellow Hemi Charger in Musclecar Enthusist had hood pins.
Any thoughts would be appreciated.

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

In my recent travels, I have seen several H.P Mopars of this era with manual or power disc brakes, but none with power drum. I am fairly certain that this car is all original except for the carb. Yes it does have the Dana 60 rear, as you will detect on the fender tag. I do have the broadcast sheet and I will enter the fender tag data here.

You're close - Germantown, but it sounds like you are familiar with the car.

As an additional follow up to the 440/375H.P Magnum Engine, my original question assumed we were only talking about the 440 or 383 Magnum engines (1 4bbl), not trips, 2 bbls. or pass, 4bbl engines. Another words the Magnum 440 or 383 engines as came in Roadrunners, R/T's, etc. I have learned a little since 1971 when I first looked at a 1969, 396 Nova SS which I initially thought had an aftermarket aluminum intake and a Holley carb. I learned at that time that Chevy produced this motor "L-78" and purchased the car with my 1962 Impala 2dr. hardtop 327/250 (small Rochester 4bbl carb)in trade. I still have great memories of the Nova 30 years after I sold it for $1500 in 1974, in excellent condition. In reguard to the power drum brakes on this Charger, it appears this set up is probably very rare. Why someone would opt for power drum brakes and not go the extra mile for power disc brakes is curious.

thanks for your help, Rick

disk brakes were too new back then and not everybody had a good experience with them. I bet his buddy had problems with a set on another car so when he ordered his he opted for the power Drum brakes.

Remember back then "New" technogly was not as desirable as it is today.

last 2 cents a lot of the guys in the know back then went with drums for less drag if they were going to run the car at the track.

I need to see line #6 on your broadcast sheet to answer the disc brake question. The A34 Super Track Pak included the power disc with the 4.10 Dana rear. The A33 Track Pak with 3.54 Dana rear may have had the same power disc option included in it. Give me more data and I can give you more answers. Hope this helps, NJSteve

The correct carb for that R/T is a carter Avs 750 cfm
