Description:

This Lotus Twin Cam engine was fitted to my F Atlantic car in 1971 and has been in my ownership ever since.  In 1973 I crashed the car and the engine then sat untouched until 1992 when a rebuild commenced.  Sadly the engine builder died and the job was never completed.  I collected the part built engine and it was then in storage again until 2016 when I decided to have it completely stripped and inspected ready for sale.

This has been undertaken by Mike Tarr at Ratt Racing, Torquay (a Lotus twin cam specialist) and is nearing completion (photos showing as is).  He has inspected all the components in order that we know exactly what is in inside and replaced any parts that are suspect.  The engine will be left with the sump and cylinder head off ready for inspection and can be completed depending on the buyer’s wishes.

This engine has not run for 44 years, as can be seen from the timeline, and the cylinder head is a particularly good example with excellent porting and none of the ravages of time.  The engine comes with the flywheel and single plate AP ‘A-Ring’ racing clutch that were fitted in 1971 when it was mated to a Hewland FT200.  There is also the ‘up and’ over exhaust fabricated by ‘Mike the Pipe’ which has some damage from the accident in 1973.
