Fine so all we need now is a 9’ 6’’ wheelbase BigJ with a 4’6’’ front overhang.Then Bewick can tell Guy to finish his order and get it delivered.
It’s actually the finale of Bewick’s wind up, regarding the anything but 9’ 6’’ wheelbase ‘240’ powered BigJ which he ordered, but which he is still waiting for delivery of, over 50 years later.
After an argument between a Cumbrian and a Black Country truck sales rep and engineer, who couldn’t even understand each other’s language and accent.
Let alone Bewick’s protestations if it will fit in my bleedin 9’ 6’’ wheelbase A series then it will fit in the identical bleedin 9’ 6’’ wheelbase BigJ which I’ve ordered.
As opposed to, the engine will fit in it and the gearbox will fit in it but they won’t fit in it together.Said in a proper Birmingham accent.
At which point SoM said fine chuck a Cummins in it but Bewick was more persistent he won’t take no for an answer to this day.
Which is why his order doesn’t show on the museum list.
Excluding fan and radiator.
Also bearing in mind that the drive axle input flange position will be ahead of the drive axle centre line.
Those combined will take a considerable bite out of the space required including the propshaft.
Ro has actually posted the chassis plans of the 240 9’ 6’’ wheelbase A series on a different A series topic but I can’t repost them here because link won’t work.
The key seems to be the 4’6’’ front overhang for the 240 v 3’4’’ for Cummins and Gardner chassis.
Which Ro erroneously describes as a ‘set back’ steer axle.When it actually means a set forward chassis obviously bringing the radiator mounting further forward away from the drive axle.
Two ERFs both K reg, NEITHER of which is an A series. They may look different, CKP250K may have an horizontal slatted grille and 7" headlamps but they are BOTH older style “LV” chassis with a short 3’4" front cab “overhang” and a 9’ 6" wheelbase. The actual chassis is different to an A series one: the rails are a different profile and the rear springhangers locate the short rear springs UNDER the chassis frame. ( Unlike the A series which locates the longer rear springs on the outside of the chassis frame. The 4x2 tractor unit “LV” chassis - like these two ( for want of a better name) could be fitted with a Cummins, Gardner or Rolls 6 cylinder engine. It was never fitted with an 8LXB. There were never any Short front overhang A series Tractor units.
The A series ( with the Horizontal slatted Grille AND the LONG 4’ 6" front cab overhang and a 9’ 6" wheelbase was available with Cummins Gardner & Rolls 6 Cylinder engines AND the 8 LXB.
A Blind man can see from pictures of the Guy Big J that it has a long front cab overhang 4’ 6". It was also availble with a 9’6" wheelbase.
The Fuller RT(O)9509A is betwen 28 & 31" long according to Fuller spec sheets and the RT(O) 610 commonly fitted to the ERF “LV” is the same length
The CM article has not copied clearly but reads 4’ 6" and 9’ 6" and is available on line.
As for the Atkinson, There was a Mark 1 with an exposed radiator Grille and a 9’ 6" wheelbase; a Mark 2 with bigger cab, a dummy radiator grille and a 9’6" wheel base . Both of these had a 3’ 4" front cab ‘overhang’ and an old style chassis with ‘underslung’ rear axle spring hanges. The bigger cab Borderer (3’ 4" front overhang) had a dummy radiator grille but had a different chassis with similar style spring hangers to the ERF A series and a 10’ (8") wheelbase. The Mark 2 and the Borderer look the same, but are not the same.
And FFS let’s not start being obtuse and nitpicking about the word overhang.

That is a Marine engine with marine gearbox.
I am not confusing the two projects, I was in a very remarkable position to see and sit in the V12 XJ220 on numerous occasions. The customer was actually allowed to purchase two of the prototype vehicles as they ere to be exported and never driven in this country unless by Jaguar technicians when they were sent back for servicing and a new fuel cell to be fitted, the customer had so much clout with all manufacturers that he had vehicles built and the tooling was then deleted so that nobody else could have similar. We used to have to provide year round support for the vehicles in one of his many garages within his country all year round, this was on a six week rotation of staff and others dispatched as required.
Fair enough CAV.
To refine the premise the A series was created at the design stage with the chassis measurement redundancy to accept the 8 LXB ‘in addition’ to all the existing 6 cylinder options.
However you look at it it’s got a chassis spacing of 9’6’’ + 4’6’’ in which to put the radiator and the fan and the 8LXB and the 9 speed Fuller and the propshaft and the drive axle pinion housing and drive flange.
Can you show same measurements for the ‘9’6’’ wheelbase BigJ ?.
The marine gearbox looks shorter than the 9 speed Fuller and there’s no fan and radiator and propshaft.
I’m wondering if Buzzer is onside with busting this myth Or was it Bewick’s dispute with Guy’s sales department over his failed 240 BigJ order.
Read Post 5452 link: 54" front overhang shown in specifications, and 9’6" optional wheelbase in text Guy Big J road test
The pre production XJ220 Jaguar concept cars weren’t what got put into production at all by TWR for the customers.
Obviously also never subject to the legal case regards same.
The ‘production’ XJ220 didn’t even have the space to fit the V12.
Which would have been expected to add weight to the customers’ legal case for return of their deposits.
No one was going to win any case against GUY because the 240 Gardner wouldn’t fit in a 9’6’’ wheelbase Big J tractor unit chassis.Unless anyone can show an additional 4’6’’ front over hang to match the A series’.
Stop that sort of talk, there are old men on here and such thoughts will traumatise them.
Hell, our hero in a pub with a half of shandy , it doesn’t bear thinking about.

I had to go out and get some more popcorn.
No need.There’s no reason why the orders list that we’ve got isn’t correct.Extremely rare doesn’t mean didn’t exist.
Foolishly I’d answered my own question previously regarding the closer front drive axle of a 6x4 unit.
Obviously if they could make the 6 cylinder options fit in a 6x4 then they could make the 8 pot Gardner fit in a 4x2.Ot was obviously a rare beast either way.
Which just leaves Bewick’s original scepticism insufficient engine supply because ERF and Atkinson was getting em.But the order sheet looks credible.
Now found a drawing which shows a 4’9’’ inch front overhang on a 6x4 BigJ tractor unit chassis.Probably to cater for the closer front drive axle.
Given a 4’6’’ > front overhang and 9’6’’ wheelbase theoretically that should match the ERF A series for space to fit the 8 LXB and 9 speed Fuller.
Going just by eye it doesn’t look like as much front overhang as the A series has.But the front panel and grille is deceiving.
The conclusion seems to be that it would have fitted in that case.
The first sentence of your post has given me an excellent idea which I would ask you to give some serious consideration ! How about you start your own “CF” site and start off by posing some of your usual drivel then you could respond and get into a right old “bull & cow” with yourself ! Only don’t be like the “Ooomegooly” bird that goes around in ever decreasing circles until it disappears up it’s own ■■■■■■ ! 
Just making a sensible suggestion !

Well CF I wasn’t going to divulge this shot and what I did with this engine because it might demolish all your diatribe about wheelbases and overhangs and the other bollox your are spouting but I did as a project remove the 6LXB from one of our Big J’s and implanted this engine in the chassis needless to say it wasn’t a roaring success and Guy Motors wern’t too happy either 
You should have put a V8 Detroit in instead Dennis 
You mean has anyone driven or seen a self propelled York semi trailer, fitted with double drive axles and a propshaft and genset engine big enough to put out as much power as Windscale power station.All fixed to the trailer by ropes.
