At the risk of offending purists, a chev 350 implant seems to be a viable
option to having my 1886 4.2 sovereign engine rebuilt. (est $8000 $AU).
Engine is lighter, more powerful and by all accounts better on fuel economy.
I have been quoted $5200 AU for new 300 HP motor - retaining jag g/box.
Any real down-sides aside from butchering a grand old lady?

Many, the car then becomes worthless, the front end will lift on the
highway, due to lack of weight distribution, you won't feel the steering
and to beat all, it will cost a fortune to do.

$8 grand for a motor rebuild is rediculous??

You can get a repo swap over in Melboring for under $4 grand.

What you want to do will cost another $5 grand to get some one to modify
it, plus an engineers certificate.

If you really want a V8 old Jag, flog that one as is and pay 3 to 5 grand
for one on E-bay.  For some reason, the people who stick chev V8's in
them, sell them soon after for half the cost.

Hey Ron how's it going?

I was wondering if you could direct me to the chap making those custom
cylinderheads for the v12?

(BTW- If someone wants to mount a chevy in a Jag then they just dont
get "it" in the first place do they?)

I Blake,

All is well down here :-)

I have not heard about that guy in some time, now.
Just did a google and could not find anything on him anymore.

If I hear about it again, I'll give you the info.

No lumpers never do.  What amuses me, is they sell it soon after
converting it :-)
Got to be something in that :-)

actual first hand experience with the swap rather than the " I've heard" or

I once put a Rover V8 and 5 speed manual gearbox into an XJS.
The XJS had been an insurance write off and came without an engine and
box.
There were no serious difficulties fitting it. I had to weld up some
exhaust manifolds (headers) out of a pile of bits of bent tube and make
some engine mounting brackets. I used the Rover propshaft shortened by 6
inches and the Rover radiator. I did without the air conditioning, it's
not needed in the UK. I had the front springs softened, shortened their
length by 2 inches and then had them rehardened and retempered.
Obviously the performance was not as good as a proper Jag engine, with a
top speed of about 115 mph but the fuel consumption was a huge
improvement. I did about 30,000 miles with it.
The donor car (Rover SD1) cost me £25

Well thats ok that you have no balls and need to ask everyone in the
world before proceeding a project. Perhaps you should extend you narrow
mind and google v8 Jaguars <its not too hard>.

I said earlier that it should be an easy project.... but  thats my
experience not yours.

Good Luck fella.

If you wish to be an idiot go look for similar idiots.

Have a look at E-bay as I said.
Many a peanut has done what you want to, and again flogging the POS.

I doubt you will fins similar idiots to you, here.

However if you are that thick and cannot "Google", try this link:
http://www.jag-lovers.org/lumps/

That forum is full of people like yourself :-)

Have a nice day!

I built a 74 XJ12L with a SBC 400. I had a lot of fun with the car. I now
have an 86 XJSV12. Sure the earthereal  smooth V12 has no equal, but the
Chevy convert had way more power (380hp) dyno tested, plus I had nitrous.
That was really scary,heh. If you want to maintain the character
of the Jaguar, the engine swap will not do that. Reliability?
Well, if you have a well maintained "real" Jag, the later models are quite
reliable. Building a "hot rod" Cheby conversion will be no more or less
reliable. If you want a fun toy, sure hot rod it. Jags don't hold their
value anyway. A really good conversion will be about 8000usd unless you can
scrounge the parts and do most yourself. It cost me about 4000 to build the
motor I wanted ,and another 2000 in running around collecting parts and
other bits, if your engine is gone so are many other parts, just getting a
new engine doesn't get you a new car. So what I'm saying is, unless it's
your hobby toy, just get a used Jag motor,Adysthemic

Well, your 1886 is the oldest Jaguar in existence, and so is
priceless....uh, assuming you made a typo, it's a 1986...then:

A V8 conversion is not "Butchery" when properly done, because no
structural alteration is needed and the vehicle may be returned to
stock. However, many if not most of these conversions are not terribly
well done, and that is one reason for their poor reputation. The
howling of purists, who have some legit objections but who on the whole
are blowing horseshit up your hindquarters on purpose to scare you, is
of course another.

Is it economic...? ONLY if you do it all (or substantially all)
yourself and do not count your own labor as a cost, but as a benefit.
Working on cars, and especially doing modifications that require
planning, metalwork, design, fabrication as opposed to stock repair, is
far more fun than watching TV or even chasing bimbos-IF you are of the
right mindset to do this work. If it isn't, you aren't.

If you do the job all the way, you will have a car that is better than
any stock Jaguar OR Chevy. Do a halfway decent job and you will have a
car with some quirks but will provide reasonable, safe service. Do the
job half-a.s and you have a deathmobile.

I bought a "Lump" at estate auction and drove it 85,000 miles with
nothing but gas, tires, oil and front brakes, and parted it out when
the tin worm had well and truly killed it. The rear end went in a
street rod, the engine and trans into a friend's pickup, and are still
running today-another 100K plus miles-with only a valve job and a
cam/lifter/pushrod kit (very cheap for Chevy). I consider that to have
been some of the best driving I've ever had, except toward the very end
when the A/C quit and the power windows did too. "Been There Done
That".

If I were to do one I would look at a Ford or Mopar engine/trans just
to be different, or maybe even a diesel. But the fact is given time or
money these hybrid cars can be excellent. People who say otherwise are
liars or emotionally disturbed agitators in my opinion.

I'd rebuild one myself just for the experience. The EFI can be gotten
rid of for better EFI using the existing manifolding, or Webers or SUs
fitted. The worthless piece of sh.t Borg Warner is easily replaced with
a 700R4 or you could convert to a 5 speed.
