The best design is the billet Animal block. Maybe one with a thicker jug, and another 1/2" taller deck.
If the cam and crank gear was bigger you could fit a even bigger stroke like the big blocks.
The billet gx200 Honda block isn't worth it. But billet heads are needed. And what we need most is a billet STEEL 2.450" stroker crank for the gx200.
Thanks for your input Charles. The blocks will be much thicker in the right areas, taller decks wont be a problem. The plan for the first prototype gx200 block it to move the cam further away to accommodate much larger stroke cranks, looking at trying to make gx390 cam/crank gears work, but it is early stages at the moment.
Billet chrome moly 4340 cranks that large wouldn't be a problem, I probably wont offer anything smaller than 2.450 for the gx200 as there is already enough manufacturers with reputable cranks of smaller sizes all ready available. As I don't want to step on any other brands toes, I just want to offer parts that are not already available at this stage.
As for the heads, my first prototype billet head wont be radical like others available, just thicker round the port area and more material in the combustion chamber. So people can port, or have a supplied ported head as they please with what ever size or shape combustion chamber they like. Radical heads like some of the rather expensive ones available will come later and will be much more affordable.
If there are any other parts for Honda based motors that you would like to see be produced please feel free to pm me and we can talk.
As for billet spark plug leads broomstick, I have completely no idea what you are talking about.
Thanks
