New 681F 'L' Cylinder Block

We can now offer for sale a brand new 681F 'L' cylinder block for the Lotus Twincam. This new block is not to be confused with the 711m Kent block currently being re-produced in America. The new 681F block is produced solely in the UK using modern materials to make it far stronger than the original. The new block comes fully machined with a capacity to be bored out to 90mm, giving great flexibility. It is also race proven, having seen almost two full seasons thus far.

The arrival of this block makes it now possible to build a brand new Lotus Twin Cam to whatever spec you wish and of course, we have everything you need to do just that!
