I don't have any good overall pictures of unmodified V8 UV drivetrains. Here's Gary Baxter's #544 at the start of his redesign.

Here's Robert Attema's #521. I have no idea if it is modified.

That last picture is the only one with a Powerglide. I see a couple of TH350s and a 4L60.
The V8 suspension is a bad design. It has 3 fixed pivots so it binds. Lower link, half shaft and upper control arm. The only thing that keeps it from tearing apart is the give in the bushings.

OMG that looks so unsafe! A turnbuckle for an upper link? [among other things]
INMHO,
Such a lot of work when they could have used a Toronado drivetrain with subframe and a reversed ring and pinion or the like

One thing you can't see from these pictures is the crazy angle the trailing arm is at and for no good reason. They could have easily mounted it at least 2" lower in the front.
They did some factory retrofits with Toronados. Never could make them cool for some reason. I don't mind the drivetrain setup. Makes it really easy to install whatever you like. The V-drive does hang down really low. It needs a skid plate.

The turnbuckle isn't a problem, just the geometry. They should have built a real upper control arm and made the half shaft a slip joint.

The front is pretty stupid too. Nice cast aluminum lower control arms but the uppers are made with 2 of the same style turnbuckles to adjust the caster/camber but they have no pivot at the outer ball joint or at the bushings so all they can do is bend when you try to adjust them. They tend to be broken for this reason.

Mark, I believe a few were made? And we know of a few also that were converted to Toro.

Thanks for the photos Joel! Is that #530, or #532?

The V8 setup was designed by factory head engineer Chuck Burgess (Peterson had left the factory by '67 or '68). Chuck is better known as the General Manager of Luscombe Aircraft during WWII. He also designed the FWD Toronado powered Tiara motorhome from the ground up during the same time frame as the V8 UV.

There was only ever one Toronado powered UV that wasn't a conversion. It was FWD, probably a Burgess test mule that was rejected for production.

After the factory closed, Peterson converted about 24 existing coaches (mostly Corvair) to RWD Toronado power, using the existing suspension and a radiator behind the right rear wheel. Many of these were later converted to V6 after the 455s overheated. None are currently roadworthy, AFAIK.

Several other coaches were owner-converted to Toronado power, and at least three of these used the full Toronado subframe. Tony has one of these which is basically roadworthy but he is struggling with the cooling. Larry Forman has another that uses four radiators to cool adequately.

That's it.
Burgess seemed to have the opposite philosophy from Peterson. The V8 mounting cradle looks like they tried to make it as heavy as possible.
