The Overfinch Discovery legend is true

[vjj]

hello Chaps

update for those following

Chevy 6.3 and most of running gear is now installed



Bulkhead has been painted in keswick green and has been fitted



Note Ceramic headers from Chevy Blazer - they are a perfect fit on the off-side but we have to chop them around a bit for the other side



Gearbox is a ZF HP22 built by Ashcroft Transmissions with stage 2 upgrade(stronger clutches, sprag clutches etc and uprated pump and govenor)together with the biggest torque convertor available and I also had a a late-type Transfer box with 1.2 ratio rebuilt at the same time.

Track day - no way!

Drag race - sure thing.

Colin I have to say that TVR engine I sold you has been transformed by the remap at Austec and the fitting of the manual gearbox.

The space mountain ride we had on Monday proved what a fantastic beast it is.

Obviously the old chrysler 3-speed was eating up the power and taking the edge off the torque but now - wow.

Your 90 is surely one of the fastest out there.

The raw driving experience reminded me of my first TVR - a precat V8S

The cam is a 265 piper - originally TVR's own grind was equivalent to a 285 but there is so much torque from mid-range I don't think that with the manual gearbox you need to change it to a torque-specific one.

See you next week

Update

coming along quite well





all engine/gearbox work done - exhaust left to do............twin stainless exiting at the back

main jobs left are final assembly and wiring and the interior.

[vjj]

Couple more update pics

All heavy engineering done

Allisport radiator in - remote gearbox and engine oil coolers in front behind grille.

Final assembly of major parts this week plus electrics

Trimmer booked for Sat 9th Feb

then off to exhaust man

Then MOT and snagging

Should be all done by end of month.

The TF kit is shorter than standard anyway and gives a 25mm drop and 25% rate increase.

I am having an LSD fitted to the rear axle and then will see what happens - thanks for the tip.

[vjj]

I was over there today(7/2/12)

Roof is on, they are finishing off the lighting loom and all the heater stuff etc etc.

I will probably get the diffs sorted when i have had a good month or so seeing where improvement is needed.

Ignore the hideous grille - it was put on for a joke.

Hi Guys

here is my first fire-up in the Landy - a bit of rattle whilst the tappets settle then boom - no exhaust yet - just Flowtch ceramic headers fro blazer K5

Eliot

can you see my lovely ceramic-coated K5 Blazer 4WD headers in the engine picture above?

Thank you for the tip.

On the drivers side they dropped in a treat but on the side in view we had to cut them an inch below the plugs, heat them up and bend them in a little to miss the chassis.

We then just welded in a bit of stainless at appropriate angles and had it coated to match - looks factory.

Electrics to finish, roll cage to go on, doors and trim to fit and exhaust and MOT.

Then it's off to scare some old ladies!!!!!!!!!!!!!

regards

Yes another one - 500i - 305 cubic inch - 5 litres - about 250 bhp and 300 lbs/ft of torque

At the time the 570 was only 2 grand more...........................................

here is mine virtually fiished

The blue manual one at kingsley cars has the camaro engine - my gold one had the Camaro engine as well - cast iron heads and hi-torque camshaft.

If the standard of their range rover restos is anything to go by then it will be lovely

Donkey apple took it for a test drive but because of his dodgy knee he found it hard work but said it was lovely.

If yours has aluminium heads then it is the corvette L98 tpi engine with a torque cam rather than a screamer.

Some photos please! Is she red by any chance?

When i took the decision to sacrifice mine for the defender build there was a bit of me that was sad - but when we lifted the body and saw the true state of the chassis(which looked fine from underneath!)and the floors I was glad I made the the decision I did.

I sent my gearbox back to Ashcroft - same spec as yours with addition of massive torque convertor - we had to make a special adaptor boss and plate as Overfinch only ever used the medium torque convertor - very naughty!
I used some new headers (from a chevy blazer) on the 90 - I still have the overfinch ones, which require a minor repair, if you want them as spares.
The rest of the exhaust has gone onto an LSE which lives in the channel islands.

It has to be said the Disco 1 is SUCH a useful vehicle - 7 seats, loads of space, quiet cruiser, superb brakes, fantastic in the winter, easy to work on, cheap parts.

Having stupdly sold my beautiful MINT jap import V8 with top-hat liners I am on the look out for a very low-mileage 300tdi ES Auto.

I saw one in birmingham with 33000 miles but the guy wanted 8 grand for it!

hi Jon

your car is a lovely, lovely thing - I suspect as part of the upgrade it has a range rover front axle with vented discs and a Borg-Warner transfer box?
I see you have LPG fitted.
Our headers do in fact match - mine are not ceramic-coated and have a couple of easily-repairable pinholes in them - they would be great to have as a spare set in case yours ever need to come off - if you fancy bringing the old girl down to Derek Allfrey Landrovers in Kirdford, West Sussex one saturday morning we could have a bit of breakfast, talk landrovers etc and you can take them home with you.
Derek keeps chevy filters, plugs etc so if you needed a service he could do that as well!!!!(www.derekallfreylandrovers.com)
We would love to see the car.
Failing that you are welcome to them if you send a courier.
I also have the overfinch spare wheel cover as well which you can have.

very interesting Jon

the difference between the Ci and HSi would appear to be the bigger valves in the angled-plug ali heads and the roller lifters and rockers.

This L98 engine was standard in the performance versions of the Corvette C4 and also the Camaro IROC Z and Z28.

This accounts for the BHP differential between the two but not the torque so they must have had a custom-grind camshaft done to get those torque levels.

The great news is that your camshaft will never wear out - you may need to change the chain at about 100000 miles as these can get a bit slack.
