Still being delayed in all of this by Ben's other involvements... but he has started on the flowbench to get some initial figures.

What he'll do is work away, logging the flow rate at each change. Tomorrow I expect to pick up a damaged head that we can afford to cut up to see what's inside and where any weaknesses might be in the porting process. There's a block too, two legs out of bed in that, we can cut a single cylinder off that to use on the flowbench to be sure the cylinder is concentric with the chamber being tried at the time.

Some further development with this. We are now looking down the barrell of marketing these engines in a variety of stages of tune some time in the new year, options to be included range right up to steel cranks. The H-section rods and forged pistons will be core components, looking at getting about 320 streetable horsepower from the 245 at 0.040" oversize bores. A lot of work to do, though, new manifolds included... manifolds that will clear the master cylinder in LHD applications, by the way.
