David Vizard bench flows a BBD 2bbl

Interesting video. I was really looking forward to this series, mainly to see what kind of ways he'd show to free up parasitic HP losses. If they end up stroking the crankshaft by offset grinding (as he mentioned they "might") then I've lost all interest. At that point it's no longer a 318, more like a 318 with a 360 stroke.
There's no way you will even get close to a 3.58" stroke by offset grinding a 318 crank.
