Thread: Ford 6 into IIA

I am helping my Dad on his 109" this week. It has a 250 pre crossflow fitted and we are converting it to C4 auto from Nissan Cabstar manual.

The 250 is fitted with a 2v head, Holley carb and extractors. Combine that with 3.5:1 diffs and it should in theory be one quick old Landy...

The Series gearbox should hold up if treated well and getting an engine is so easy, the only problem is the conversion plate. Finding one is a bit tricky. It's not a registered vehicle and I don't plan on getting it registered for a good while so engineers certificate isn't a problem if anyone has any advice that would be great.

Hi , have a look in here;

http://www.dellowconversions.com.au/...Automotive.pdf

on page 24 they list Falcon 6 cyl into Series 1, 11, 111, Landrovers

Hope this helps, Cheers Jeff

I used to have a ford 250 powered Land rover ( althogh it was Stretched to 145Inch wheelbase)
It had adequate power was a great tow vehicle but with standard ratio diffs it returned 10mpg ..........on the other hand it did not matter whether it was towing or cruising mpg never changed
So it was converted to gas with 2 gas tanks .Plus the 3 petrol tanks it cost an arm and a leg to fill

Well I'm sure the 250 has plenty of grunt, fuel isn't a major issue it can't be any worse than the 3.5 V8. The 2.25 uses a fair amount of fuel anyway for no get up and go. Did you need to modify much on your chassis, I'm going to try and use the Series gearbox, it should hold up as long as I don't go full throttle and dump the clutch. I was thinking the injected 250 crossflow would be good but a carby fed 250 would be good cause of the simplicity. If anyone has a conversion plate if you put up some photos up of the plate or conversion that'd be great.

I have a wreck down the back with a Ford 6 in it. I used the box but the conversion is still there. Bit far to send it but I dont want it.

According to Wagoo on this forum;

"2nd gear is the culprit that kills most series gearboxes. All Series gearboxes suffer from shaft flex under load when in 2nd and to a lesser extent 3rd gear. The old Series 1, 2 and 2As would on occasion break the layshaft in half or sometimes even the mainshaft due to fatigue from running flexed.
Series 3 boxes use a more rigid gear cluster instead of a layshaft with slide on gears that the earlier boxes used. The cluster didn't flex but the mainshaft still does, and this flexing is centred under the 2nd /3rd gear bronze bush (distance sleeve), in many cases breaking the bush in half and/or thrusting against the spring ring (circlip) which normally only receives thrust loads on over-run(coasting) in 2nd and 3rd gear. The circlip and or groove in the shaft end up slightly tapered and the circlip can spring open.
The less frequent need to use 2nd gear with a more powerfull engine may actually contribute to better gearbox reliability if the vehicle is driven sensibly." Wagoo.

A very wise man is Bill! I am going to do his New Process gearbox conversion when I get the time, which will handle any engine without fear of breaking,

Well I wouldn't mind that conversion plate but as you said its a bit far to send. If you could find some photos of the conversion that'd be great. If the series box doesn't handle the power and torque of the 250 I might use a toploader box with a series t/case adaptor that way I could drop in a lot of other ford motors in the future (eg. 302, 351) But I heard that the Series 3 box is the weaker box and the late IIA is the srongest but it could be different. I wouldn't need 2nd as much cause it would probably ldle in 3rd but you can take off in second very easily with all that power and torque. The back axle may not like it but if it lets go I've got a salisbury axle sitting around.

I've got the dellow/ford conversion on my S3 as you've seen in my "old car new owner" thread.

I think the biggest issue with the ford conversion is that the exhaust manifold is on the wrong side so the exhaust has to pass very close under the sump. I may be a little over cautious but I don't like the thought of the oil being heated in the sump.

I'm looking at the Valiant/Hemi option ATM.
