A 250 or 302 single rail is rated to 285lb/ft, similar to a stock T5.
A 351 single rail is rated to 325lb/ft which is the same as a Z-type T5.
A std. wide ratio Toploader is rated at 375lb/ft and a bull nose 425lb/ft.
 
BW single rail differences.
All have same mounting flange, which is the same as the 3 speed box except for one bolt.
Valiant has longer, finer input shaft, same output I think.
Valiant has a short shifter shaft with a dogleg intermediate rod to clear the Valiant crossmember.
Valiant has 2.84 first gear, so does cortina.
Cortina has foward mounted shifter and short shift shaft with no intermediate shaft, extension housing is different to cater for this.
Falcons all have rear mounted shifter and long shift shaft with no intermediate shaft.
There are several ratio sets in falcons, from 2.54 first gear fitted to 351s, to 3.47 on xf type sixes.
The highest torque rated box is the 351 at around 350lbsft.
 
BW single rail.
Valiant has 23 spline input shaft which is longer than the Falcon/Cortina box
Valiant has different extension housing with different mounting and shifter to Ford types.
P76 single rail is very similar to Valiant type, not seen many so couldn't say exactly what the differences are, if any.
Repair kits should be the same, but you'd need to be a bit careful when its comes to extension housing output shaft seal.
As far as I know all Valiants had same 2.84 first gear ratio gear-set.

Falcons and Cortinas have quite a few gear-sets, I know of -
2.54 first gear (for 351s) also highest torque handing because of larger input gear.
2.84 first gear seen in Cortina six
3.06 first gear in 302s and six's until XE
3.54 first gear in later sixes.
One extension housing in Falcon with corresponding shifter position.
One extension housing in Cortinas with corresponding shifter position.
 
This is what I was able to find off the net, and from books in the local library, for the 0503 :-

Falcon XA & Leyland P76
2.78/1.93/1.36/1.00

Falcon XB & Charger E48
2.82/1.84/1.32/1.00

Falcon XC/XD/XE
3.06/1.84/1.32/1.00

Valiant VJ-CM
3.32/2.00/1.43/1.00

Falcon XE (4.1 carb only)
3.43/1.99/1.43/1.00

However, Ford used a 10-spline 1&1/16th" input shaft, but Chrysler and Leyland used a 23-spline 1&1/32nd" input shaft.

Other XE Falcons got the "new" 0506 4-speed, or it's relative the 0507 5-speed.
 
Single rails came in 4 variations depending what engine they were designed to be fitted behind. All are physically identical on the outside and are interchangable. To check which type you have, look at the small tag on the side of the box.

Work has 2 I loads. I wouldn't buy one. Both have had engines under 100,000ks and parts like turbos have cost us a bomb. And frankly one of them has been babied and still the same crap.
We run a fleet of mostly Sprinters and a good 315 or 316 is hard to been. Obviously size is an issue but our Vito's have been good to.
Hiaces are still reliable but then they aren't for touring.

I honestly love my Ex Ambo 315 I take it to Phillip island on weekends and its ridiculous how comfy the captains chairs are and how quick the 4cyl is.

I have a work van, I can't decide if I like it or dislike it

Mechanically it's reliable, 210xxxkms of delivery driving and it's never had a mechanical failure.
Electrics play up occasionally, and parts can be tricky to come by - even for Repco.

It's an oddly comfortable vehicle too, although you sit on the seat in the car instead of in the seat in the car - if that makes sense. It's probably a common van seating position.

They basically just remove the rear shelving units and communication gear flashing lights etc

It's good that they keep the fitout with all the goodies. Cop cars get stripped out completely.

Yep lifted a lot. Our standard order vans are completely different (more comfy in the back I bet) but the captains chair makes you forget it all. These get all the extras though. Rear separate aircon compressor glove box fridge. And a sporty spoiler hiding the massive fans. The spotties side and rear a good on early mornings

I've ridden in the back of one of these and it was like riding in a billy-cart. Did they have stiffened suspension or something for ambo duties?

My Daily. 315 ex ambo. Would make an awesome camper

my work van is a deisel turbo auto toyota hi ace,its hard not to smoke it up after a bit of rain,not sure what diff ratio is in it but has massive torque

Yeah we have had a few of those. We had a petrol on hit 700,000ks before getting side swiped. Great little vans.

Exactly what happened at work. Boy was that a smokie test drive.

They are a ginormous hunk of shit. You are better off blowing your money on drugs and alcohol. At least you won’t suffer while wasting your money.

If it has no low-end grunt and seems to rev fine over 5000 without sounding like a piston is going to fly out and remove your pancreas, it's a 200

Sent from my CPH1607 using Tapatalk

Yeah a few of those things are true for mine. Stuffed old carby, stock headers and shitty twin system, currently had no thermostat and i run 98 petrol.
I've bought the thermostat, I've got a full exhaust waiting (need headers actually) and I will overhaul the carby.
 
I have a spare 600 holley off my 350 chev land cruiser I may rebuild.

Better yet is not having a fuel gauge as well. Just fill it up each trip. Pretend its not taking that much. Happy.

You beat me to it.
 
My Clevo drinks more than a fish. I choose not  to know its lack of economy!

I think the phrase 351 cleveland and economy don't compute comes to mind.
 
I'm glad my ZH doesn't have a trip meter.

I've wondered the same thing, especially since 302 Windsors are so much better on juice than 302 Clevos. I have a theory: that many of the clevo's faults conspire together to make for poor overall economy
 
• 351s are all open chamber (with poor efficiency) unless they're early 4Vs.
 
• they run high oil pressure
 
• large main and big end bearings, causing extra friction
 
• despite large ports, they are inefficient and have dead spots (yes even 2Vs), atomisation suffers. Exhausts are poor too.
 
• on 302s, factory piston to deck height is huge, resulting in poor quench action. Zero decking helps a lot.
 
• factory timing is very conservative. Advancing a few degrees helps, especially if running 98
 
• standard camshafts are retarded from '76 onwards, which is bad for efficiency.
 
• they're a physically big engine with a large surface area, losing a lot of heat from combustion.
 
• they're cold-blooded: 82 deg thermostat means that even more heat gets lost to the radiator.
 
• crank and flywheel are heavy, with lots of inertia to overcome
 
• They're a race engine de-tuned for the street.
 
In your case Gspec, it sounds like you need a new carby. Thermoquads were considered pretty good on fuel and while the above reasons would all explain bad economy regardless, 30 l/100km is just ridiculous. You might actually have a flooded or stuck float.
 
Instead of trying to find bits for it and fix it, you'd actually be better off screwing on a clapped-out eBay Holley. My 600 vac was an $80 gumtree special and got 17 l/100km with just a bit of jetting. Not great but at least average.

my mild 302C with 650DP, 2800 stalled C4, 4.11LSD, 27" tyre, 100km/h at 3350rpm uses 23lt/100km,
Has only been tuned for Drag Racing, have done 17.8lt/100km but not sure how.
 
Bros 302C ZH with 350 holley used 15.3lt/100km going to the AFD last year with a stuffed slipping C4, 3.00 9", 245/60r14's
