I think a compromise with rod length would be more in order, running a long rod will reduce side wall thrust, but will also slow down the piston speed vice a shorter rod. The slower piston speed can have an effect of making the torque curve more "peaky" and not quite as flat. And yeah, the longer the rod, the more barrel shims you'd have to use to maintain the proper deck height, so your compression wouldn't run away with you. Anyways, a really cool discussion, glad this came up :-) Regards to All
