Hot Rods Jaguar powered hot rods

So do a triad of 2" SUs, with their vacuum chambers polished up!

Our Welsh friend is correct. Run a mixture gauge off an O2 sensor on the exhaust manifold, and use the data you get from that in real-world driving to generate a custom needle profile, and your SUs are as good as EFI - except they won't go 'pfffft' when they get wet and strand you by the roadside

 

Word Ned - going to run my 357 Pontiac on SUs eventually.

 

Very reliable engine; but not pocketbook friendly if they do break. Also not a lot of fun adjusting the valves.

Why is everyone bashing the carbs??? They are much easier to tune than a Holley, even the three carb set. A carburetor mixes fuel and air. The SU's do it very well.

One suggestion: when you need an oil change, try to find a shop advertising a "six cylinder special". Just make sure they don't specify the number of quarts of oil.

I've actually been planning on doing this exact swap. Was thinking of something like a 37 Ford, satin dark blue, reversed chrome wheels with an XK 6 in it with polished triple SUs and Polished cam covers would look and work very well

FWIW, the first Jaguar DOHC inline 6 is known as the "XK" engine, made from 1948 to 1987, and they really are wonderful engines. Few simple ways to keep em happy, ANNUAL coolant changes (Can you say head studs that run through coolant p***ages?), DO NOT overheat them, DO NOT run 5W30 or 10W30 in them, they think that's penetrating oil. Like others have said, the biggest problem that Jaguar have in America is that people **** with them that don't know what they're doing, they're really amazingly well engineered and if you know what you're doing, very reliable. Side note: Jaguars, in race circles, have a very enviable reputation for reliability.

One concern on an XK is easy to fix ahead of time and prevent; once the tappets get some wear they can come loose and grenade things. http://www.jag-lovers.org/technical/tappet.html

SUs are great carbs, people are probably thinking of the 67 and later cars that used the POS Strombergs, which do ****.

A Quick way to pick up big power on an E-Type V12 is to throw webers at it. I have owned a couple of Es, the 74 that I had with Webers used to haul serious ***. I'm partial to Jags tho as I have always had em, my other O/T DD is an 06 XJ8, bulletproof reliable car, corners like a sports car, 0-60 in 6 secs and 29 on the highway, bought it 3 years old for under $22k, **** buying a Camry

 

This Chevy Fleetline was built by Kenny Thompson, one of our greatest fabricators. It is one of the coolest cars I have ever seen......and it's V-12 Jag powered....done about 20 years ago when it wasn't cool. It has two Holley carbs.

 

Found it. It isn't a Model T. Just looks like one. It's a home-built woodie body. You can find it in the December 2009 issue of HRM.





Sorry these were taken with my camera phone. I'm not cool enough to own a scanner yet.

Oh.. And.. Umm.. I retract my statement that it had all those Model T stuff as well.

I feel dumb now. Haha.

I know this is an old thread but this has to be the car in the Glen Pray estate. There can't be too many 40's trucking around Tulsa with Jag sixes. I worked for an old employee of his who claimed another built the car in the 50's and that it had do***ented drag and salt records. It is supposed to be forsale for $20,000 but it is all second hand to me and most likely a somewhat "padded story" given it's origin. I've never seen the car and was told it is now a well weathered maroon but was gloss black in it's day. Hopefully someone gives it a good home.

 

Saw a 57 Jag MK VII with a 283 and a powerglide.

 

never knew there where so many guys around with jaguar powered hot rods
usually they trow the jaguar engine out and drop a small block in it
i seen the dragsters mostly from england , the even was one with a propane system racing
and a v12 t bucket in the eighties , back then theres even a v12 trike running around in france
http://www.collectioncar.com/files/gazette28-91286111439-TrikeV12_07.jpg

i purchased a 3.6 jaguar AJ6 , its one of the last 6 inlines made by jaguar
the engineblock originally was intended to be a diesel as whell as a gasoline engine so its been made incredibly sturdy
verry strong crank and the main and rod bearings are actually overlapping there so big , you just cant possibly bend or crack it
the newer engines have an all aluminium block with cast iron liners so there a lot lighter too
newly desighned head with 4 valves per cilinder
they allso made a supercharged version of the later engines in the x300 and eeeeh i think it was aston martin but im not sure
the camprofile is a little on the dated side and you can get some extra power by upgrading those (good luck finding racecams for it though) , you can have the orinals reground to a better profile
theres allso some power to be gained by porting the intake to the ports a 3 angle valvejob and use a little more lift
the first ones used a hot wire style airm***meter that was verry restrictive
another nice thing to know : some jaguars (usually the v12's) where fitted with th400's
the housing is different but the inner workings are the same as the gm stuff
the later supercharged stuff and the 6.0 v12 got fitted with the 4L80E
same thing as with the th400 outside is different , theres allso a different plug for the electrics
those transmissions will bolt up to most jaguar engines so no need for adapterplates if you can find a jaguar one in the states

my plan is to build the jaguar AJ6 and 4L80E intoo a 1978 chevrolet pickup and maibe turbocharge it at a later date
both the engine and the trans will be running of megasquirt stuff

still trying to find out if the torque converter from jaguar is the same as a GM one
the reason i like to find out is theres no stuff aailable for jaguar but theres some aftermarket converters with higher stallspeed for the 4L80E GM versions

 

this engine is lighter than the old one too , should be verry possible use the older style pistons and to bolt the old style head to it for those wanting the cl***ic look but not the weight

 

Here's a Brizio-built Jag-powered Model A RPU:

 

after following all the links posted i found out another nice fact :
the front crossmember with all the suspension gubbins will fit good in an older truck
still looking if the old one is the same crossmember as the later AJ40 and x300 jags if so i would have a good suspension with the correct enginemountings a upgraded anti rollbar and rack and pinion steering
sofar i found the trackwidth might be 4 inch too narrow when mounted under a 1978 squarebody

 

That rpu is in one issue of rodder's journal.

 

Good looking engines IMO, but having worked at a Euro repair shop I had the displeasure of working on them quite a bit. They have their own qwerks and you have to get to know those SUs intimately.

 

You haven't been here since February of this year .... as well ... these pictures are 6 years old .... just wondering if there have been any updates with this ? >>>



Apologies for energizing an old thread HAMB'rs ..... but this one is too cool to p*** up. I've been plenty patient.

 

Well; I'm not gonna apologize for reviving a dead thread. I'm still sitting on a set of XJ6 drivetrain and suspension and interested in any potential cars/trucks to swap it into! Was even considering building a "Kougar" knockoff.

 

Great to see this again it was beautifully built and widely featured in uk magazines in the early 70s in and is important in the history of the uk scene.

Jaguar powered Anglias andThames were quite common in the early uk rodding scene in late 60s early 70s.

Perhaps less so now.

I will try and find some old pics from back in the day to post once I work out how to do it.

Alley Cat possibly belonged to a guy call Steve Gillam or Gilliam.

 

The Jag suspension is great under anything from about '41-up (it's too wide for the earlier cars) and isn't all that expensive to refurbish. The engines, not so much. The V12 is heavy (800 lbs, and it's all aluminum!!) and difficult to work on (you need a special fixture to remove a head). The inline sixes are better, but don't expect parts to be either cheap or easy to find. Overheating one will usually kill them (they like to drop valve seats). The EFI on the later ones will be either Lucas or Marelli, both are troublesome...

 

The blower was set on top (fake) but this car was built from an XK 150 using the engine, trans and suspension. I think around 1961 or so.

 

Like this?

 

Budget-sized Blast-o-lene special! That's a cool rig right there. Still trying to find a way to use this stuff while it's still good.

 

so I just got one of these gorgeous motors !
I have always loved these things and never thought one would find me .
And as I see it , it’s perfect in a speedster ( using this term loosely )
Hoping to replace cam covers with the old style ones without the ribs for starters
Heck that thing could just sit there and I’d be happy seeing it every day!

Great 6 cyl engines but Lucas electric's let them down..12 cyl engines make great power but mechanical repairs are astronomical..one part ie: oil pump $1600....ouch....need special tools for repairs....
