Another year down the track...
Now the information from somebody about camshaft flexing (and how he deals with it) leads me to decide that we'll change the firing order.
Instead of 1-5-2-6-2-4 we'll have 1-2-3-6-5-4, that will remove the problem of the two cam lobes each side of the distributor gear on the camshaft opening and closing simultaneously. This means we can probably retain the gear drive for the oil pump on the camshaft and save outselves some trouble with oil plumbing.
We're getting close to finalising a piston design and getting our first batch made.
