need help for six conversion into Jaguar XKE

[Anonymous]

Hello,

I know you all can help me with my dilemma. Currently I have a 1968 Jaguar XKE which was the victim of a hack 302 conversion. Whoever decided to do it believed in cutting first and praying that it fit. The resulting structural integrity was far too compromised for my liking. Rewelding of the pieces is the only option and eliminates the possibility of a v8 (due to the width of the engine bay). So the v8 was pulled out and a better option had to be found. I decided that a Ford inline six would be the way to go since the four speed manual transmission and driveshaft were already in the car and reasonably attached. What I need is the length from flywheel to end of the front pulley and engine height from the pan to the top of carburetor for the 200, 250 and 300 six. My objective is to fit the six in place without having to cut any more supports or creation of hood scoops which will upset the whole aesthetics of the car. Any help would be greatly appreciated as I would like to get a Ford powered six cylinder Jag on the streets in the near future.

Thanks,

Travis Sneed

In order to get some respectable power out of the engine (like it would have had originally), you'll effectively be restricted to the 250/300 engines.

It sounds an interesting project; down here an OHC Ford six with a turbo might be an impressive package, but I guess this isn't really on your list of possibles...

Good idea, if your not a purist Feline Lover. People used to put Pontiac OHC's in these things!

Dimensions of the 300 I6 are here on this forum, check this link. http://fordsix.com/forum/viewtopic.php?t=3281&highlight=300+six+dimensions. This is not the best link. One other guy posted a superb link with factory drawings in four views early 2003, and I cant find it.

There are two sumps...the F150/Bronco style, and the passenger car LTD/Galaxie Big Six (240) one which was around in limited numbers from 1965 to 1971 ish.

As for the 250, I've only got the Aussie 250 figures. There are as near as dammit for your needs. The US 250 is about 1/4 inch taller.

Length (balancer to rear bell mounting where the transplate bolts on)=30.11", that's with the balancer, not including the power steering pulley.
Height (maximum, from base of sump to top of rocker cover)=23.6", but more like 27.6" with the carb and slimest air cleaner you can get, more if its the US one. Oil filler cap gets in the way on log headed US 250's.
Length (from water pump flange without a viscous coupling mounted, to the bell mounting)=31.11"

Pans for the 250 are front mount, and span 8 inches below the 9.47" block. The first bulge reaches its deapest 13.4 " forward of the bell housing, then keeps flat until 21.7" forward of the bell housing. Unless you find an Aussie block, a silly idea altough someone had one with a 2V head for sale here, which has a front and rear mount sump available. But it'll fit...the XKE six sump was massive!

See this link for US 250 modified to fit Fox body Mustang. http://fordsix.com/forum/viewtopic.php?t=1085&highlight=250+fox+body

The 200 is just ~1.64" shallower in the block, at around 7.83". And the front water pump and balancer doesn't jutt out as much. Have to wait for a 200 expert to reply! It's super light.

There are two versions of the 200 with different bell housings. One is very close to the small block Ford's six bolt design, but has the bolts second from the top bolts mounted down slightly lower, and the flywheel needs a 2.75" bolt spacings rather than the SB, 240/300 I6 and 250 Fords 3.0" pitch centre spacing. The other bell housing is a four bolt affair, and is not going to fit without modifications.

In my opinion, the 300 is the best option. It's got a similar deck height, shorter by about 3/4" at 10" from crank centre line to headgasket. There is not a lot of room for the carbs, but a 600 cfm carb on a Offy intake would be okay. The rev limit should be okay at 5000 rpm with the right cam. So long as its not the early pre-synchro 4-spd, the trans did service behind the V12, and is okay to 295 lb-ft of torque. I've seen a Panther J72 with a battallion of Weber carbs doing well over 330 lb-ft taking one of these, but they are not a super strong box beyound that.

As a previous owner of a '67 E-Type...a word of advise. DO NOT weld or braze the monocoque members that make up the front structure of the car. These should be replaced ONLY!. or you will have structural problems galore.
If the previous owner was enough of an A$$ to cut into these things he should have never been allowed to own a Jag.
XK Unlimited in San Luis Obispo in California carries these members. They ain't cheap but there is no other way to go.
Putting a 300 CI Ford Six should not be an impossible task. A 200 CI Ford with an Aussie head and triple SU's might also be possible, tied to a T5 Borg Warner 5 speed transmission it should give you a beautiful car to drive.

Boy Do I miss it!

It can be done. Here's an example. Tim sent me these photos for a webpage I'm building.

Jack,

What Ford six cylinder is that in the Jaguar? 300ci? After the measurements everyone gave me, it seems the 300 would be a tighter fit than what you can see in the pictures. Do you have any more info on this car and who is building it? The work looks quite impressive. I would like to thank you and everyone else who saved me a lot of time from being in junkyards trying to get the measurements!!! I'm sure I will be asking many more questions in the months to come.

It looks like a Small block inline with a Australian 250-2v head.

I'd say it's a 250, not a 200. Incidentally, that head is the closest I've seen yet to the correct colour (barring my own paintwork).

Cheers, Adam.

I believe it's a 250
