Well, I'm gunning for 600 hp and the gear ratio choice is severely limited for the 741 casing.The 741 is the case that A bodies came with, EVEN with 383's. Nothing wrong with them.

3.55 or 3.73. I have an Auburn diff I will be using. Shipping would be to Illinois, container from there.I only have 1 spare 489 center. Bet it would be $$$ to ship to you. What ratio you thinking of going to?
Wisconsin to Illinois should not be to bad for shipping...3.55 or 3.73. I have an Auburn diff I will be using. Shipping would be to Illinois, container from there.
Packing it well isn't all that easy, though.Wisconsin to Illinois should not be to bad for shipping...
@memike got a tutorial a few years ago on differential packing!Packing it well isn't all that easy, though.
I would be tempted as well. Pick it up and wait months to pay him for the work done so far. "I'll pay you tomorrow"So my painter has been explaining for two weeks he would paint car tomorrow it is next etc etc. Drove over to his shop today, car still in primer. He explained he got behind again and I was only two away from paint. I am very frustrated. I simply turned my back on him and walked away, I just could not even speak. Nothing I could say would help the situation. Driving back to North Dakota I have made a unemotional decision. If Demon is not painted by Dec 1/I will trailer it home and paint it myself in my shop. I am loathe to do that as I have painted several at home and I am just not set up to do it. I really wanted a better job on this one. My tolerance for being jerked around has met its end. I am a patient guy and had you told me I will paint it 12/1 I would be fine. But to continually be told I am painting it tomorrow and not paint is just plain wrong. Thanks all for letting me vent.
Those ratios are available for the 741 case. Mopar 8 3/4" (8.75) Ring and Pinion for 741, 742, or 489 case3.55 or 3.73. I have an Auburn diff I will be using. Shipping would be to Illinois, container from there.
Wrap it in plastic, put it in 5 gallon bucket, fill full of expando foam. That’s what I did for the guy I shipped one to in Brazil.Packing it well isn't all that easy, though.
I did not know this. Thanks! I only searched summit and jegs (a good while back) and only found 3.23, I believe, which is what I have. Hm. That changes the equation slightly.Those ratios are available for the 741 case. Mopar 8 3/4" (8.75) Ring and Pinion for 741, 742, or 489 case
That’s a great solution!Wrap it in plastic, put it in 5 gallon bucket, fill full of expando foam. That’s what I did for the guy I shipped one to in Brazil.
Are you gonna be running wide, sticky slicks?Not changing the rear end is a bonus in several parts ways. I suppose I can go with the one I have and see if it holds up.
Use a Home Depot bucket, they’re heavier duty than most others.That’s a great solution!
Good question. 600 horse and a 8 3/4 regardless of carrier might be a push. Especially if there's traction involved. Pettybludart ended up with a Strange S60 (Dana 60) in his 408/ 1966 Dart. The 8 3/4 wouldn't handle the power. It's a drag car though.Are you gonna be running wide, sticky slicks?
I went Dana 60 as well. My 440 will be pushing that 600 figure as well. You could build an 8.75 and on street tires, I think it’s hold up with a 489. I don’t think the 741 will last as long but something to consider is that there’s guys making the Ford 9 inch handle 8-9 hundred HP. And the pinion on it is even smaller than the 741Good question. 600 horse and a 8 3/4 regardless of carrier might be a push. Especially if there's traction involved.

Smaller but a extra pinion bearing. That's what makes the 9" so strong.I went Dana 60 as well. My 440 will be pushing that 600 figure as well.

The other question is what transmission and how hard of shifts? A manual trans is generally gonna transfer more power and more shock to rear end than an automatic where you lose 15-30 percent of the power. So in theory you may only be seeing 480-520 hp at the rear wheels versus the 580-600Good question. 600 horse and a 8 3/4 regardless of carrier might be a push.

Wonder if a quality machine shop could add a pinion bearing to the carrierSmaller but a extra pinion bearing. That's what makes the 9" so strong.
You would have to have a specially made pinion gear.Wonder if a quality machine shop could add a pinion bearing to the carrier
