Hi all,

I have a question.about axle packages on 70 E-body Hemi cars.. or more exactly no axle package on fendertag. (see pic for example) Is it 3.23 open gears automatically.. or could it be differential with 3.23 ?


Thanks
Nicklas

No axle package would be a 3.23 gear and I believe with a hemi it would have had a sure grip as standard .


running up my post count some more .

unless specified on tag or build sheet.
3.23 is standard ratio. Even with hemi.

And im not so sure suregrip was standard unless ordered even with hemi auto..
I could be wrong on that account.

1970 Challenger R/T 3.23:1 OPEN is the STANDARD gear ratio & was not dependent on the engine

the OPTIONAL HEMI engine did not change or require any additional rear axle OPTIONS

the fender tag would not indicate if the subject HEMI R/T was 3.23 OPEN or 3.23 with the OPTIONAL Sure-Grip (~$42) - it would be noted on the window sticker and broadcast sheet

Funny but it was true at least for a '68 Hemi Road Runner that a friend bought new back in '68. Bare bones no radio, rubber floor mat, RM21, column automatic. I've told the story before when back in '69 my friend was tuning my '69 RR and had the distributor out and on the Sun distributor machine when I got a call that my older sister had no way to get to work and needed me to take her there. My friend said "take my (Hemi) Road Runner. I jumped in it, took off to pick up my sister. I picked her up and jumped on the throttle and it lit up and I looked in the inside rear view mirror and shock shock shock ONLY ONE TIRE MARK! confused confused shruggy Got back to my friends shop and asked if something was wrong with the diff and he said, "nothing wrong just the standard 3.23 OPEN 8-3/4". My '69 383 RR that he was working on I ordered it with the 3.91 axle package, 727, Air Grabber etc. so I was shocked the Hemi RR had a 3.23 OPEN axle??? Fast forward and a local friend gets a numbers column auto '68 Hemi RR and when he first got it we were talking and he says to me "Mike you're never going to believe this but this Hemi RR has ........." Before he could get the words out, I say " A 3.23 OPEN 8-3/4 rear axle" "How the #3LL did you know that????" he says? "Long story" I said wink grin

(Side note on how we think we know everything even when we're young. When my friend back in '69 with the '68 Hemi Road Runner pulled the distributor out of my '69 383 RR (727) he was sure I got hosed by the dealer and was thinking one of the mechanics stole my original distributor probably when they did the dealer prep. He was sure it should have had a dual point distributor instead of the single point he pulled out of it to tweak. Nope the automatic 383 RR's had a single point distributor. I was a little upset until I checked the specs, no biggie wink )

Here's a '68 Hemi Road Runner with (AXLE code 48) 3.23 with Sure-Grip............Sure-Grip must have been a lot cheaper in '68 versus '70 laugh2

Having had several '71 GTXs, I was always surprised that they had the heavy duty suspension and torque boxes but only an open rear standard. Must have been a way to get a couple more bucks for the SG option while keeping the base sticker price as low as possible.

Just seems weird for muscle cars to be peg legs especially given the fact that they were so traction compromised to begin with. Did the other manufacturers do the same thing?

My take is that the hemi was 1st priority when ordering, but the options kept upping the monthly payment. So staying with the automatic meant a cheaper rear axle.
and so all the money available went to the hemi option. Everything else was upgradeable (more or less). The whole deal was purely economical.
I've wondered how many dealers actually stocked a hemi for the lot, when so many seemed to be pretty bare bones

You don't have an "axle package" but if you look at the build sheet it will tell you what it came with.

IMO not only for economics but what if the factory guessed wrong on what the customer wanted for an axle ratio? I would think that out west with many open roads and highways an automatic with a 4.10 ratio for travel or daily long distant driving is not so ideal. Also my friend with the bare bones '68 Hemi Road Runner got it bare bones because he drag raced and had a 4.56 complete axle sitting in the shop for some reason wink grin And yes I know that the 4-speeds came with a standard 3.54 Dana axle (My '69 4spd GTX has that). A 3.23 axle ratio with Sure-Grip was really great and very nice to drive in my '68 Road Runner (383) and at 55-70 mph it was "pleasant" enough for my wife and family going cruising. $$$ and application or do like I did back in '69 when my dad gave me the look as the salesman asked if I wanted the standard 3.23 open axle package and I said "No I want the optional 3.91 Sure-Grip" and turned to my (co-signing) dad and said "I want and need it for the hills and snow dad" with a slight grin. (lived in southwestern PA at the time). He knew as he was a mechanic and IMO gear head too. smile.

Yep, my 67 S/S 396 Chevelle auto had a 12 bolt high 2 something open rear, and the 70 Challenger HP 383 4 speed had the 3.23 open rear. Then my 70-1/2 Z28 auto had a 4.10 posi 12 bolt. Basically if ordered it had the posi, off the lot, no

the DANA60 was a MANDATORY extra-cost OPTION on 4-speed 440 & HEMI cars (the 4-speed was no-charge '68 & '69)
