Why aren't you just returning it to the 'professional' guys who built it?
Seems silly to be pulling apart a motor that's under warranty.

I have not used compressed air in years for doing stem seals. Length of thin poly rope fed through the sparkplug hole. Wind it up to tdc and your sorted.
The wind down style clamp above works well but buy a good one as tough springs can open the fingers.

Yeah, seen them, looks like you tap down on the retainer, and the magnets draw the collets out. Must be a hole in the side of the tool, somewhere, as you get stubborn keepers sometimes.

These work well, (with air in the cylinder)
 
 

thats only for borgwarner autos not FMX/C4 etc 
the gears run the opposite on these so the gears teeth are cut the opposite angle

This list may be helpful for some,
to achieve an accurate Speedometer, vs chosen diff ratio and wheel/tyre size.

it's been done, i like the 1UZ turbo for gemini though

 

 
wheres the turbo...

 

Yes I do have pictures my transit is my daily driver
so it is in a bit of a mess but I plan in the next year or two
to start a full ground up restoration keeping the over all
outside look like it was when new
I don't know how to put pictures up so as soon as
I can figure that out I will post them.
 

Update to progress

So with Christmas, Holidays and all, I have managed a little bit of time on the old XF. I have managed to:
- install the 1/2 cage
- install the second (passenger) seat
- rebuilt the rear brakes
- installed a new rear handbrake cable (this was missing entirely)
- changed the rear trailing arm and Watts Link bushings for Nolethane (they were stuffed)
- changed the Swaybar links and bushings, am going to run the factory swaybar for now!
- removed the tow bar from the rear bumper (cut out the actual towbar)
- rewired the engine bay to a distribution block for positive and negative and;
- have just relocated the battery tray to the boot (where the spare wheel used to sit).
Am getting there!

For a light flywheel i am impressed with mine. 6.5kg with ring gear on.

Hello
I just found this post and signed up.
I have a Genuine 3.2 tonner MK2 van with its original owner book and an original factory service and repair book
my Transit came out with a 250ci cross-flow but they also came in the 200ci cross-flow  mine also had a 3 speed
floor shift manual box it made my transit scream for more gears at 80klms I now have a 5 speed ford toploader
out of an XF falcon so now I have a van that can do 120klms without to much effort  but usualy I drive at 80 - 90klms.

So...avgas ftw?
Haha
Seriously though thanks for the info, not above doing whatever work is necessary. But i am going to try the adaptor and 4barrel route first.
End goal is still efi itb's. But a lotto win or other windfall will be in order for that to happen.

Good info as per usual.

Adapter is the centered type.

Is the adaptor offset to one side (ie the 350 pattern lines up with 2 bolts and 2 barrels on one side)? Or is it centred like the one in that video?

If it's offset, it would be ideal for mounting the primary on the engine side (bowl clearance permitting) so the secondaries get a clear shot at the plenum. Now that you have a spacer under the carby, you could use that extra clearance to make the turn softer. I would mould some epoxy filler into the transition to achieve this.

If it's the centred type, neither mounting direction is better, ie: both primary and secondary barrels get the same sharp turn into the plenum. I would still take advantage of the extra volume given by the spacer to mould a bit of epoxy in there to make it a gentler angle into the plenum.

Thought about running an adaptor, have had one a trademe watchlist for months. Just did not think too much about it.
Makes sense though and can easily ream out the holes.
You guys are awesome as usual!!

Thunderhead289 (YouTuber) did this on their Satellite revival. 318 hemi (I think) worked a treat.

Could you flip a 2-to 4-barrel adaptor to run a 570 on your existing manifold, with a carby spacer to help with the transition? You could do a bit of throating out and smoothing of the plenum to help turn the corner. Just a suggestion instead of starting from scratch with the manifold

Gerg, i thought i may be pushing as far as freebie apps etc go, i am more curious than serious about the old girls output.

Running a 500 Holley at the mo so it is a peashooter in comparison to alot of the machines on here.

With what specs I could find on yours 10.9?:1, 230@50 .553" guessed 2200-5500, 5300 peak on the Kustom Bitz dyno program,
(street head) 245hp@5300rpm 286ft/lb@3200 (Race Head) 270hp@5300 305ft/lb@3500.

There are a few calculator programs you can buy, but they are complex and need many inputs to even be in the ballpark.
 
As for free online ones, it's too much of an ask to offer these carefully developed programs free to the public.
 
There are some simple ones that you can use and just keep changing the figures to suit your estimate, using VE as a pecentage of peak torque.
 
Most engines, unless highly modified, will pretty much make the same torque at an rpm range that the chosen camshaft will dictate. So if you know the peak torque of your engine standard, and you know when the peak torque rpm of your cam occurs, you can extrapolate from there what the power will be at that rpm and taper it off toward redline.
 
So if you're sitting at about 80% VE at peak torque, and that occurs at say 3500 rpm, you could assume that it will drop to say 50% at a 5000 rpm redline (as the engine runs out of breath). So it's taking smaller gulps but more often.
 
This is assuming that you have an optimal induction system (ie not a peashooter carby)

I thought the D head was similar to the C2/C2A head around the 43cc mark, A stock C1A I measured around 47cc
My CNC C2 with sharp part of the chamber rounded off & EVL valves (have a dished face) was measured at 49cc,
Ported & shaved XD head I brought off Sean/Clevo120Y is 50cc,
Off memory Standard XD/XE/E1 55-57cc, E2 50-52, C1/C1A 48-50cc C2/C2A&D 42-44cc, there's a old thread on here that has chamber CC's listed.
 
Kustom Bitz has a free dyno program I've been playing around with for ages, Runs in Excel. http://kustombitz.com/g/9081/fun-free-stuff.html
There was a thread on here(or XFal) years ago about it. Put in Engine Ci & comp, Cam @50, lift & rpm range.

Yeah, had some wrapped around my diff in the old XD. 🤣
