rt options

[charger01]

What exactly were the minimum options an rt had that made it so.  Was it the 440 , larger fuel line, an extra spring in the rear.  Just kinda curious every rt had to have?

[1970chargerrt]

440, special cam (as compared to say a 440 station wagon motor), duel exhaust, 3.23 minimum rear end (I think sure grip was an option) and heavy duty suspension (thicker bars up fron and SS springs rear) are the performance related items I can think of.  727 was standard and 4 speed a no cost option.

And bigger brakes!

It wasn't a set of options - it was a package that included certain options. The R/T was only available with the 440 Magnum (standard) or the 426 Hemi - and neither of those engines were available (in any form) on a non-R/T Charger. A Dana rear axle standard with a 4-speed transmission and optional on an automatic (pretty sure you couldn't get it on a non-R/T at all). The suspension and 11" drum brakes were part of the package to handle the extra power and weight. The rear springs were stronger and had more leaves but were NOT SS springs. You could order front disc brakes which would then revert the rear brakes to 10" drums. Emblems of course, and bumble bee stripes that were available only on an R/T (or some very limited special versions like the 68 Bengal Charger).

good info....I had heard ac wasnt available on certain models as well.  That true?

To elaborate on what Troy stated.....

Well, not so much models as that of drivetrain configuration. You couldn't order A/C in a R/T when either the car was (426 auto/4-speed) or (440/4-speed) equipped. Also, for '70 and '71, the 440 six pack was a new option. Like the 426 Hemi with either tranny in earlier years, a (440 six pack auto/4-speed) equipped car couldn't get a/c. 440-4bbl auto cars without the Super High Performance axle package (4.10 Dana) could get a/c.

Were SS springs optional?  My 70 R/T has SS springs (half leaves in the passenger side and less full leaves in the passenger side as compared to the driver side) and I'm pretty sure they are original to the car. 

The rear springs were stronger and had more leaves but were NOT SS springs.

Now why exactly couldn't you get A/C with the 4 speeds?  I can imagine you couldn't with the hemi because of its size but what keeps the 440 from having A/C?  A 383 4 speed could get it and it's the same size!

Not sure "Why",  but I'm sure the engineers thought with the horsepower rating, the genre-nature of the 4-speed wrapping out the rpm's, A/C was the last thing on anyone's mind with such an order/purchase...

I'm only guessing since I wasn't there.....

Those are not Super Stock Springs.. Those are your standard HD springs that came on 440 4bbl, six pack and hemi equipped 2nd generations. My Daytona, C500 and R/T's all had the same springs.... 5 1/2 right, 6 left

Up to 69, Only the Hemi had the larger fuel line (3/8"). The 440 had the same line as the 318/383  - 5/16".

They did have the 3/8" sending unit on the tank though with the return line for the R/T only vapor separator.

I had always heard that it was to keep from overrevving the A/C compressor - but the 383 will actually rev higher than a 440 so I have no idea. You can't fit it on a Six Pack because the air cleaner is in the way (same as the 2 speed wiper motor).

the engines were better built as well , as well as the better cam there was better valve springs , timing chain ,  exhaust manifolds , higher compression pistons , H pipe exhaust , heavier connecting rods , better mufflers , bigger clutch , higher stall converters , oddly the rad / HD cooling pkg was still optional , you could get a R/T with a 22" rad

[Troy]

Man, how could I have forgotten the transmission? An R/T with the manual transmission would have gotten the 18-spline 4-speed instead of the 23-spline 4-speed or 3-speed found in non-R/T cars.

I don't really count the exhaust manifolds as an R/T option since the 383 HP used the same ones as the 440.

The Hemis got a whole bunch of specific parts on top of the upgraded R/T components (wheels, body stiffeners, specific auto transmission OR clutch/bell housing/flywheel/starter, mufflers, etc.).

Don't forget about the windage tray and dual point ignition.

Just to throw this out there - on the early 70s Challengers they treated the R/T package very similarly to the Chargers, except that the 383 Magnum 4bbl was the start of the R/T level rather than the 440 Mag.  This causes a lot of confusion because some people mistakenly think a 383 Magnum Charger is a factory R/T.

Dual point only on 4 speed R/T's.

The R/T was only available with the 440 Magnum (standard) or the 426 Hemi - and neither of those engines were available (in any form) on a non-R/T Charger.

I'm still a member of the non-R/T HemiCharger camp...

[miller]

I thought the R/T came standard with a front sway bar...

[bull]

My 383 car did too. Maybe the 318 and 225 cars didn't.

[hemigeno]

Sway bars came standard on all Chargers in '69 anyway.  On other B-bodies it could have been an extra-cost option depending on which engine the car was equipped with, ordered as Sales Code S13 H/D suspension package.  S13 came on every Charger though...
