Hello, I started planning a conversion of a 70’s Chevy Eldorado convertible, and wanted to ask a few dumb questions please:
1. This car weights 4700lbs as-is, and probably 3000lbs after the original engine, gas tank etc will be removed. What is the minimal size of motor and voltage that are recommended here? How do you calculate it?
2. For a decent range of 200 miles, what is the battery capacity that is calculated?
3. I assume that I leave the transmission, correct? If so, do I need to lock it on a certain gear, or do I just leave it as-is?

Thanks for helping me here!

Sorry to be the bearer if bad news and I would never want to squash anyone's project, But...

It is Front wheel drive automatic?... Not sure there is any easy way to get the motor to work. Supporting the trans would also be more weight.
There may be a way of getting a dual shaft motor, (one side to each wheel) but then there would not be any way of reducing the gear ratio.
VERY heavy... 200 Miles would be a BIG stretch even with a complete Tesla setup.

Please keep us posted if you decide to take on this interesting project.

Um...I believe Cadillac built the Eldorado (not Chevy)

Maybe (2) individual "big/beefy" motors (that are strong enough to handle not having any gear reduction)
...(1) connected to each axle
...& controlled by dual controllers

Plus, a "boat load" of batteries (about the size of a '70's "Cadillac" Eldorado)

Others may be able to advise on size of motor(s), voltage & capacities required to (try) achieve your goals

This is the same topic as the same member posted a month ago:
Classic Chevy Eldorado conversion

He apparently didn't like the way that one went, so he's trying again... although I don't know why because he apparently didn't even read the responses carefully enough to note that he has the wrong car brand (yes, an Eldorado is a Cadillac, and while there were Oldsmobile and Buick versions of this model there was never a Chevrolet). Anyone want to guess how interested I am in doing the same work over again for him?

It is Front wheel drive automatic?
Yes, all of them are front wheel drive and automatic, with a longitudinally placed engine and a famous - but now obsolete and obscure - variation of the Turbo Hydramatic transmission.

There may be a way of getting a dual shaft motor, (one side to each wheel) but then there would not be any way of reducing the gear ratio.
The alternative would be the unnecessary complication of two sets of reduction gearing, one for each wheel... but I assume that the point of this suggestion was just to fit a motor in at the drive axle location without using any kind of transmission.

Even if one were willing to running a motor at wheel speed (which would be nonsensical), using one shaft end of the same motor for each wheel (on the same axle) would not allow differential action... fine if you're drag racing, but useless on the street.

Yes all knowing Brian.....

You missed the point of my responses.
Since no one has answered I was attempting to start a discussion with OP.

"It is Front wheel drive automatic?"
I was asking to see if the OP knew this.

"There may be a way of getting a dual shaft motor, (one side to each wheel) but then there would not be any way of reducing the gear ratio."
Once again to see what he knew or what he has explored so far.

Since you have a handle on everything...
I will take my expertise elsewhere.

The questions have already been answered, in the other thread. I understand that you probably didn't realize that at the time you posted.

"It is Front wheel drive automatic?"

I suggest not asking questions to which you already know the answer - it's just a waste of everyone's time. If you want to know if the OP knows that the Eldorado is front wheel drive and automatic, try asking "OP, do you know that the Eldorado is a front wheel drive automatic?" Asked as it was, it looks like a question to the group about the vehicle, with which you may be unfamiliar.... it is an obscure model.

And he should know - both aspects were covered in detail in the first thread on this project... an illustration of how this second thread is a waste of time and effort. I suggest reading the first one to minimize the redundancy, if you want to contribute.

"There may be a way of getting a dual shaft motor, (one side to each wheel) but then there would not be any way of reducing the gear ratio."
Once again to see what he knew or what he has explored so far.
Once again, I suggest asking, instead of suggesting a configuration which is not workable, and which the OP is not considering, causing nothing but confusion. We're all adults having a discussion - there's no need for clever interrogation techniques.

Since you have a handle on everything...
I will take my expertise elsewhere.
You have expertise, as seen in other posts, but we haven't seen that yet in this thread. Why not share that expertise (as you have in other threads), rather than asking obtuse questions?

While I am participating in this discussion for the benefit of anyone else who may run across it, I'm not inclined to go to any effort to help the original poster (who seems to have no appreciation for those who respond to his queries), so you should help him.
