I looks as though I may be in the rare situation of having seen numerous King K components as well as a handful of Simon’s K engines.
I have met with Simon a couple of times and seen a number of engines components and few completed engines. I understood that he was intending to build a few K engines to different specifications to demonstrate that the engine can be reliable and durable. I have not seen his completed large capacity engines however along with a few others I have seen some of the components he believes are appropriate to improve on the durability and reliability of the VHPD and some other tuned K engines. Some of these are prototype components others are now finalised.
He believes that he has demonstrated what can be achieved with a rebuild based upon a VHPD and has completed this using mostly standard components as well using his own specification of liners, flywheel, seals etc. His focus at present is on designing the components for large capacity K engines.
He has a broad selection of worn and failed engine components, including, pistons, liners, blocks, heads, flywheels, cranks, seals etc which he has used to investigate wear and design issues.
I have seen his baffled wet sump and the dry sump as well as the lightweight flywheel with integral ring gear along with the dual plate clutch and release mechanism. I have also seen the familiar Omega pistons and Arrow rods as well as the various liners, including a selection of Chromoduro liners machined to his specifications. He also has a number of custom designed windage baffles as well as various oil rails including ones manufactured to his specifications. These also include oil jets to cool the pistons. He also has a selection of long bolts of different specification.
He also has various head gaskets including the Rover MLS gasket as well as one manufactured to his specification. Simon has some valve train components manufactured to his own specification as well as numerous heads which he has modified. There are various intake manifolds, spacers, adapters, air boxes and trumpets which he has designed and built.
There are several blocks which have been blueprinted as well as sets of plates to simulate the assembled stresses these blocks would experience such that they can be accurately remachined.
I have also seen the drawings and the pictures of a crankshaft which he is having manufactured. I understand that a lot of time has been spent optimizing, refining and validating the design. The crankshaft looks like a complex work of art.
I do not have the answer to the question of where have all, Simonï¿½s, King K, engines gone. I can only bear witness to the fact that I have seen many of the component parts of the larger capacity engines and from what I have seen it will only be a matter of months before he has some of these engines running. Hopefully some of these components will improve the reliability of the K engines and become available to the many of us on modest budgets that may choose to improve a VHPD or other K.
