For those wishing to complete the task themselves, the best guide is the book by Peter and Valerie Wallage, Rebuilding and Tuning Ford's Kent Crossflow Engine . This is a great book for anyone interested in the Kent motors. I have previously used this as a guide in rebuilding a race motor for a 1969 Lotus Type 61 Formula Ford. In addition, Jake Lamont and Tom Andresen’s book entitled How to Build and Maintain Competitive (yet legal) Formula Ford 1600 Engines , is a useful source, although more limited to Formula Ford motors to Sports Car Club of America (SCCA) racing rules. In the present case, for time limitations, it was decided to have the engine rebuilt by Farley Engines, Inc. The company owner, Curtis Farley, is one of the most respected names in building racing and performance engines in the US.

The oil pump and filter bracket was destroyed as a result of the distributor melting onto it ( [link] ): it was therefore, removed ( [link] and [link] ).

The thermostat housing ( [link] ) was badly corroded to it was removed, as was the thermostat itself ( [link] and [link] ). The corrosion of the water passage was no more than expected from and engine of this age, offering hope that no internal damage had been done by the fire.

Disassembly of the engine indicated that at some point in its history it had been head ported ( [link] ) with dual valve springs installed ( [link] ). In addition, +.020 pistons had been fitted and a high lift cam. All of these modifications would have significantly increased the power over the stock Cortina motor. Interestingly a lightweight alloy flywheel had also been fitted in place of the standard unit.

It was known that the carburetor had melted and run down the intake manifold. Removal of the manifold showed that some molten metal had run into the engine past at least one of the intake valves ( [link] ). One result of the complete tear-down was that it was possible to see the location where the molten aluminum from the carburetor had flowed through the intake valve and onto the piston ( [link] and [link] ).

New and replacement parts

In addition to a complete rebuild of the block and head, several components were replaced by either new or used items. Since the 1600 Ford crossflow engine installed in my 1969 Lotus Seven S3 had been converted to dry-sump for racing several components were known to be in good working order and used for the present engine. The replacement items included:

it is a goid question and i want to know the answer as well
Do somebody tell me a best nano engineering book for beginners?

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
what is the actual application of fullerenes nowadays?
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?

good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world
