More thanks for your car's resume and your great build progression. Very refreshing to see serious tech on here.
I think you and Morris have achieved the most success for road racing Cobras with the difference being yours is in more of a conventional configuration. You both agree on many points like starting with a KMP, stiffness, power required and lightness.
Just to pick your brain, an all aluminum, 9.5 deck small block (of 358 to 427 ") would weigh in around 470 pounds. Why such a modest power figure (650) when with Cup technology (na), you could achieve 730-800HP and a conservative 9000RPM top?
It's great reading your experiences and views.
