unless you mean, use the bike engine to generate electricity

I was joking ;)
But you can do the same with an EV package which should be easy

Only restriction is space for batteries

I would suggest that the rear suspension mounts are inadequate to support a motor/ transmission loads and would need redesigning and refabricating. It would be much easier to transplant a drivetrain into the front end.

Oh, and integrating the BMS and drive control with the current canbus would certainly stretch the ingenuity. An electronic handbrake coupled to the drive control would be needed to bring the car up to modern standards too.
The only way that this could be even vaguely economic economic is if you value your time at 1p per hour.

I can agree to a certain extent in respect of the stsndard suspension bushes
as they're rubber, and they twist/wind one way then the other when it's
put under load or unloaded, ad that is what gives them a limited life.

However...the SuperPro replacements are poly bushes with a central bar
that is 'free' to revolve around the bushing via lubricant, so it doesnt
wear out like the original bushing.
And the actual axle beam is very sturdy and more than capable of having
electric drive motors adapted to fit to it, though l have to admit that there
might need to be some redesign/modifications to the floorpan for clearance...

Yes the Canbus would have to be replaced...obviously..but hey..
anything is possible, and l for one would rather the original
engine bay be used for a big battery pack and electronics to give it
a better range rather than try to cram the batteries in the interior
or even the boot...heavens no...where would you put the shopping
or luggage.

Crazy G so just by looking at the rear axle you can tell that it's sufficient for all the drivetrain loads, and i suppose the monocoque passes your torque sensing eye as well.
Without the canbus, the entire electrical system would have to be redesigned , or do without the 2006 electrical gizmos . It's now 15 years later and cars now have far more sophisticated amenities

Forgive me, but I didn't ever say I was an 'expert' and know all the "ins and outs"
that there may or may not be. I expressed an idea, a thought, a suggestion, call it
what you will, but not a set in stone 'this is exactly how it is going to be done'.

We are discussing possibilities here....guessing, speculating, provoking thoughts...
as that is how and where ideas are formed and formulated and plans made.
Perhaps someone with 'the knowledge' and/or inclination might look into what the
rear axle can or do or cope with...or if it can possibly be 'adapted'...it is not for me
to say it can or will be.  I have worked on them, so i have some intimate knowledge,
but not of the stress mechanics etc...but there is nothing wrong with thinking that
it might be possible ?  But forget it, perhaps someone who does have the necessary
qualifications might look into it, but if not...so what...it was just an idea.

Today, almost anything is possible. Not that long ago it was never thought possible
to land on the moon using a computer that had less capability than a Comodore,
yet we did it, and we've even sent a remote controlled vehicle to Mars !  And all
because someone thought it was possible..suggested it..worked it out...and did it.
I guess they were criticised too.

Cars of all ages are being 're-energised' with electric conversions everywhere, by
experts and newcomers to the electric conversion game.
And yes..they are having to replace/rewire complete electrical systems as they go
about it, with some being brought more up to date by having 'gizmos' and the
'sophisticated amenities' added that you mention..but only IF the owner wants
to have them added, although to be honest I have noticed that nearly all of the
vehicles that I have seen on related TV programmes have tended to stay as close
to the 'original' as possible.

But back to the topic of this thread....Battery Packs....anyone else have any ideas or
thoughts etc that they want to say....but please, no more about my 'idea/thought'..thanks.

The Chinese company Nio are already offering a car with interchangeable battery packs, as well as a network of fast charging stations. How extensive the network is already ,I am not sure,but it's an awfully big country with ve
extremes of climate and terrain and population densities so I doubt if it's ever going to be the whole country, and it would certainly be more sensible to fly the distances involved .

Here's a link to a homebrew conversion of the older Colt model (not 454 related) done bunch of students in Ireland, 10 years ago!:

https://dit007pureelectric.webs.com/progress.htm

Hey, top speed 40MPH with a 40 minute runtime, but it shows how straightforward it is to meld an electric powertrain into an ICE car. They did a great job, and with better parts and better batteries, it would run more like a professional conversion.

10 years is a VERY long time for this type of tech and no doubt you can get much better parts now, whether off the shelf, or just by looking for wrecked EVs to buy at auction and grab bits.

It's just an example, but there's no doubt in my mind that someone could convert the 454 to electric reasonably cheaply if they had the time, tools and inclination. What your time is worth is another matter, but many of us have nothing but time right now. Lockdown at home time.

Thanks for the great link El Tel, and what a wonderful story to read/follow.
It clearly shows that anything can and is possible....even way back in 2012 !

Today, there would be many differences, not least in the battery department,
and that technology is still advancing.  I have to conceed that retaing an FWD
power source would look to be the way forward IF anyone tackled a 454, but
a thought that crossed my mind is how to retain a similar braking capability
what with the weight of the batteries but no servo assistance. But I'm sure
there's an answer to that, I just haven't the time to look into that at the moment.

Bigger brakes? I saw another thread, by JJ, I think, where a large set of race-grade wilwoods were somehow wedged into the 454, if memory serves me right..

(edit) - my memory did serve me alright there, here's the link

I have a set of those on my Brabus too....
But my question or thought was...how do you get the same level of braking
as per the original IC powered car when there is no vaccum take off for a
brake servo, and therefore no 'assistance' that is/was required to apply
the necessary 'force' to pressurise the brakes ?
Fitting larger brakes isn't necessarily the answer, or is it when they would
require additional 'mechanical assistance/force' as per a servo.
Then there is also the potential issue that bigger brakes won't fit within the
original wheel hub diameter....unless one had 16" diameter rims (as I have
on my Brabus with the Willwoods) or 17" diameter rims as per JJ's Brabus.

My 'limited' knowledge of EV's is that when one removes one's foot from off
of the accelerator pedal that the motor then becomes an alternator and 'feeds'
charge back into the batteries.....so is it used as a brake as well, and/or how
is it or does it apply braking as well as feeding energy back ointo the batteries ?

Would someone be so good as to explain; in simplistic terms please; just how
the EV setup works, so that we can all have a better understanding of it, as l
am sure there are many who don't 'really' have a clue or comprehend all the
intricacies of the setup. Such an 'explanation' would I am sure be of benefit
for many to then have some idea of what it is all about and perhaps pass
comments or ask questions etc etc.

Regen braking is a feature which is inherently built into electric motors. Really old electric cars needed you to flip a switch (think: down hills) but modern controllers make the process automatic when you take your foot off the pedal. So for all intents & purposes, auto regen-braking is a feature which is determined by the controller you use with your motor.

As for the brakes themselves... EV brake booster / electric vacuum pump...

I cannot, but I found a pretty good diagram which shows all the main bits you'd need:
