Some Thoughts On Slant Geometry

Tony - I think the engineering is sound - but the issue will always be the head arrangement and lack of potential. What you propose, at least in my head at 10pm on a Sunday, will simply put you in the "not enough port" zone earlier. It might hit harder, yes. But it won't run out as far. If I understand you - the 170 platform might make better use of the head but you still run out of air at some point. If it was me I'd probably gear it to get past the low speed issue, and run a transmission with enough gears to keep it between that low speed issue and running out of port. Rather than sciencing further on the engine, science out more downstream in the powertrain...
