Yes, the Cams are to be welded-up and retain the AAC. We are going from 1678.6cc to 1846.7cc with a combo of both bore & stroke. The compression ratio goes up as well. While all this goes up, we will do everything to lighten the crank, rods, pistons and valves. Everything I do has reliability and broad powerband in the goals. For racing down the strip, this should be a beast. For riding to work and back, I am hoping this will be quite manageable day-to-day. Those are the goals anyway.
I suppose, that the modifications of the A.A.C and the cylinder heads are done on our own parts
. I understand that you are considering a slight increase in displacement: 1800cc.
From 1679cc you need 3mm more bore for 1790cc. I have even opened this engine several times over the past twelve years, and I don't think there is enough material for rigidity.
Increasing the stroke may be good for the couple. I think that for the Vmax, favoring a large torque at a rotation speed that is not too fast will be a good option.
You are the expert (I am only an amateur) when do you think?
